The engineers and musicians at the session all took turns checking out the LCD-3s, and they were all knocked out by the sound. They weren't audiophiles, but they all heard the difference great headphones can make.
To put the LCD-3's sound in perspective, I borrowed the engineer's Sennheiser HD 650 headphones ($650), and it was really shocking how much better the LCD-3s were. The HD 650 is a great set of headphones, but it sounded small, thin, dynamically compressed, and its stereo imaging was relatively flat next to that of the LCD-3. Both headphones were played with the same Grace Design m901 headphone amplifier.
The LCD-3's dynamic punch is simply the best I've heard, bass definition and power are phenomenal, stereo imaging is remarkably open and spacious. No dynamic headphone at any price comes close to the LCD-3's sound. Some audiophiles think the Stax SR-009 (US$5,250) is the best sounding headphone on the market; I don't agree...... the Stax SR-009 lacks the LCD-3's power, dynamics, natural midrange, and potent bass.

Clearly, the Audez'e LCD-2s pushed all the right sonic buttons for me. Those planar drivers produced a relaxed yet detailed and natural sound that just seemed to unite my ears and brain. The LCD-2s are well made and beautiful -- I love that real wood -- and they're comfortable to wear, making long listening sessions possible and all the more rewarding. If you're lucky enough to own a pair, you won’t feel the need to upgrade anytime soon -- if ever.

the LCD-3 doesn't even really require additional amplification beyond whatever your source device of choice is capable of providing; sensitivity (93 dB/1mW) is high enough that you can drive it with an iPod,
they have a handmade feel that says "old-school radio engineer." They're certify handsome, and quite comfortable as well: the pads really do a great job of supporting the heavy cans, and they keep a good amount of airspace between your ears and the drivers, perhaps contributing to the perceived spaciousness of their sound.
I'll just come out and say it: this is certainly among the best headphones I've ever heard, and perhaps the best, handily outdoing old personal favorites like the Denon D7000, with which it shares an uncanny ability to render room ambiance and recreate a convincing soundstage, but with more controlled bass and just plain better sonics across the board.
Vocals: male and female and acoustics are spellbinding.
Bass: everyone knows that these headphones can do bass, but they do more than bass, they flesh out the texture within bass and respond to complex bass rhythms without muddying the lower mids.
Room acoustics: are incredible, eerie vocal placement and staging ,
Personally I am a fan. I liked the original foam headband but this one oozes luxury. It is padded and sits comfortably on my head.
everyone knows that these headphones can do bass, but they do more than bass, they flesh out the texture within bass and respond to complex bass rhythms without muddying the lower mids. There is no bass hump and I know that people have described them as emphasizing bass notes that aren't really there ?? not sure what that means but my interpretation is that the LCD3 reproduce a very real , almost palpable bass which some headphones just don't manage to portray acurately.
more forward voiced than some of my headphones which are probably a little recessed. Vocals (male and female) and acoustics are spellbinding. I had heard some metal at RMAF and as I didn't know what I had listened to , called on a friend for guidance to test these waters. The experience of Katatonia on the LCD3 is quite something. Not sure if this is what the band expected people to listen through but remarkably well recorded. Overdriven guitars without additional distortion and lightning quick response to some really complex harmonies. I have heard this about metal on the Stax O2 too.
this was a criticism by many of the LCD2 but I never found the highs to be particularly rolled off. Thus when the rumours started that the highs were to be more extended with the LCD3, my concern was that they would be too bright and not to my listening preferences. They do have more extention but they are not bright. They have an almost ribbon feel to their top end which is crisp and airy but never bright or overbearing.
The LCD-3 has a coherency, transparency and top to bottom consistency of sound that rate it as the very best headphone I have ever heard.
The mids are surely beautiful, while not sounding colored in any way. When guitar has bite, the LCD-3's reproduce the bite, but not in a way that's painful - in a way that seems always very natural.
The combination of the neutrality and transparency is an outstanding retreival of detail and resolution.
All well recorded material sounded really, really good, and in fact, was the best I have ever personally heard from a headphone, including my beloved Sony MDR-R10.
The LCD-3 handily beats the Beyer T1 (which is a headphone I like a lot). I prefer the LCD-3 to the HE-6 as well, and even prefer it overall to the MDR-R10. Does that make it worth the asking price? For me, beyond any shadow of a doubt.
I like dark wood, and I prefer the darker wood of my original LCD-2 over the Zebra-wood of the LCD-3. The wood finish is nicer on the LCD-3 to be sure, but I like darker wood. That’s just me, though. Many will like this look better. The dark brown leather is VERY nice looking, and matches the grill color well. Judge for yourself: The LCD-3 comes in a ver nice wood box, and includes some leather conditioner, as well as balanced and unbalanced cables.
I hated these when I first got them because I was using Tesla T-1's before. If you listen to these right after the Teslas they sound dark but I kept coming back to them because the Teslas bump in the high midrange fatigued me ears.
It's almost like you have to change your views of what a headphone should sound like if you are used to headphones designed to "sparkle". I have been through many headphones and always thought that highs that "sparkled" made listening fun but there was always a recording that had too much sparkle and hurt my ears. You will not have that problem with the LCD-2s. The highs are there but don't have that high midrange spike that some other phones do.
I finally decided to give these a really good listen after putting them away time after time t....everything sounds balanced now. The bass is very good but does not get so sub-woofer like that it overpowers everything else. (I had that problem with Denons on some recordings)
The longer I listen to these and get farther away from the Beyerdynamic sparkle the more I like them- especially for rock because I can crank them up louder than the other phones I have owned. (Probably a bad thing actually- I will have to fight the urge to do it)
I like the soundstage- instruments are pinpoint placed. It is also wide enough for my tastes.
Another thing I really like- great recordings sound awesome but bad recordings are also OK especially stuff that has lots of highs that kill other headphones designed to bring highs out.
My favorite thing about these headphones is the way they do female voices. Absolutely buttery sounding once I got the midrange adjusted to my preference. Alison Krause's "Forget About It" album is really good through these.

One result of the combination of the neutrality and transparency is an outstanding retreival of detail and resolution.
I prefer the LCD-3 to the HE-6 as well, and even prefer it overall to the MDR-R10. And folks, that’s saying a mouthful. Does that make it worth the asking price? For me, beyond any shadow of a doubt.

Audeze’s LCD-2 is hands down one of the five best headphones Playback has ever tested. What is more, recent driver revisions from Audeze may mean that the versions you would buy could sound even better than our review samples did, which is saying a mouthful. If you are shopping for a true top-tier class headphone, you owe it to yourself to hear this one before making a final decision.
Just at posting time, Playback learned that Audeze had made a running production change in the LCD-2, introducing new "Revision 2" drivers said to subtly alter and improve the overall voicing of the headphones.
EXTENDED REVIEW: When I was given the opportunity to review the newly released open pair of EL-8 headphones by Audeze, I literally jumped at the opportunity. I have been a really big fan of Audeze’s products going back to their initial big release of the highly vaunted LCD-2s several years ago. Audeze has certainly come a long way from those early days with the release of several new products such as the LCD-3, LCD-X, LCD-XC, and their new headphone amplifier/DAC: the Deckard (review upcoming in the next few months). The LCD-X’s are currently one of my very favourite open-backed headphones and are one of the most revealing reference level headphones I’ve come across. I was very curious to see how the newly released open-backed EL-8s performed in comparison. Coming in at only $699, the EL-8s come in at a considerably more affordable price point than many of their current LCD series offerings.
The EL-8s, like their other headphones, utilize planar magnetic drivers and unlike traditional dynamic drivers, can offer quickness, detail and extremely low distortion. Designed by BMW Designs, the EL-8s are a drastic departure from their current headphone styling and I have to say that I am very impressed with the build quality, materials used and overall construction. They have improved upon both the comfort and weight of the LCD series with these new headphones. The open EL-8s come in at only 460g now and while I was rather ambivalent on the comfort levels of the LCD-2/X/XC/3 headphones (as I found them neither comfortable, nor uncomfortable), I am quite happy to see that design care was used to ensure that these headphones would be more of a better fit for a wider audience.
Overall, I am very impressed with the build quality of the EL-8s. Both the form factor and comfort levels seem to be taking Audeze in a bold new direction. These headphones are designed to be more portable than the LCD Series and I can confirm that they certainly are easier and lighter to carry with you. The headphone cable itself took this design requirement to heart and it is both light and flexible and a perfect length in my opinion (2m; not too long and not too short). It is terminated with a 1/8” stereo headphone plug and comes with the larger ¼” adapter. However, what is different here is that the output plugs from the headphones have changed from their standard mini-XLR terminations to a new Audeze proprietary connector; so you might have to wait a bit for any custom cabling.
I have been a big fan of planar orthodynamic headphones for several years now. I find the sound that they can portray very natural and as true to life as it gets when compared to the more traditional cone-style dynamic driver. The open EL-8s continue in this tradition and have included some more technological enhancements. They do continue to use the “Fazor Technology” waveform guide that we first implemented with the LCD-X and LCD-XC headphones and I’m quite happy to see that this technology has flown down to the EL-8s regardless of their price point. The “Fazors” are acoustical elements positioned on either side of the magnetic structure and serve as waveform guides. In the end they enhance transparency (particularly in the upper mids/treble region based on my personal experience) and offer improved sound-staging and openness of sound.
Along with the Fazor Technology design elements, the EL-8s offer Audeze’s new “Fluxor Magnetic Technology”. This allows the magnetic flux density to be essentially doubled. So with more magnetic flux, the more control of the drivers are achieved (even lower distortion).
As well, the driver has been redesigned and this new “Uniforce” diaphragm utilizes variable trace widths in the voice-coil to effectively capture variations in the magnetic field by better balancing the forces of the individual traces and thus create a more uniform force density across the entire diaphragm. With this uniformity comes even lower distortion. In the end the numbers tell the tale, the headphone impedance comes in at 30 ohms and the efficiency is a whopping 102dB/mW. While they are rated to handle up to a crazy 15W, I can play them very effectively out of any my iDevices with complete ease and full enjoyment due to their very high efficiency.
For the purposes of this review, I used the EL-8s in several different configurations; from directly out of my iPhone 6 or iPad Air, to my Astell & Kern AK100II portable player, to my Resonesssence Labs Concero HP, right up to my main headphone rig: Metrum Acoustics Hex DAC and HeadAmp GS-X Mk2 desktop headphone amplifier. In terms of source material, I threw some of my favourite recordings through my CD player and digital files (either 192kps high resolution or Apple Lossless) at the EL8
My first listen to the open version of the EL-8s was through my primary “on the go” DAP: the Astell and Kern AK100II. As the cabling of the EL-8s only currently allowed for single-ended operation, that’s what I ran with. I immediately threw on El Camino by The Black Keys and thankfully my ears were treated with the very ethereal and natural Audeze sound that I’ve come to know and love over the years. The bass drum thundered when Lonely Boy started up and very much reminded me of the thump from the much higher priced LCD-3 or LCD-X. Oh so satisfying and they (EL-8s) were still very controlled and defined. My previous experiences with headphones wrongfully led me to believe that I could have one or the other, but not both. Audeze’s products have shown me time and time again that you can in fact have your cake and eat it too.
Deep and wonderfully rich bass that hits on a level that is rarely exhibited, but also the details are never smeared, nor is there any distortion that inhibits one’s ability to make out even the tiniest details at the lowest octaves. Subsequent frequency sweeps down to 20 – 30Hz show that the drivers on the EL-8s never run out of steam and are fully present. I find the bass is like a good foundation to the music on which the higher frequencies build upon and thankfully that is still certainly the case with the EL-8s. I find their bass has less of a full sound down below when compared to their most excellent LCD-X. But the LCD-X’s come in at more than 2.5X the price of the EL-8s. Overall however, the bass quality and quantity of the EL-8s are very satisfying and very natural and offer incredible performance (especially in the sub $1000 range).
Vocals on the open EL-8s are equally enticing. Josh Groban’s new album “Stages” sounded absolutely stunning. His voice range is truly a site to behold and the EL-8s certainly did him justice. The inner details of his vibrato to his impressive range were all portrayed with incredible realism that left me completely satisfied. I find that the EL-8s are voiced most similarly to the LCD-X in the Audeze line-up and my thoughts were cemented when I heard this new album with these great headphones. I’m a big fan of bossa nova and the open EL-8s continued to impress when I threw in Diana Krall’s “Quiet Nights”. Diana’s voice was as seductive as ever! It was neither too up front, nor too far back, but rather in almost perfect place with the rest of the sound scape. Again, the smallest inner-workings of her voice were portrayed with incredible realism that left me again thinking: “I can’t believe these headphones cost only $699”. While not cheap when compared to the headphones one can purchase at BestBuy, when you compare them to many other top of the line flagship headphones, they give you more than 85% of the performance at more than half the price!
Finally I pulled out an old standard of mine that I haven’t listened to recently. I’ve been a trumpet player for over 35 years (but it’s certainly not my day job). Wynton Marsalis is one of my favourites by a good margin. His technical ability is virtually un-paralleled by modern day standards and when I heard his “Flight of the Bumblebee”, I knew I needed to find another line of work as I could never approach that level of sophistication. Classic Wynton is a fabulous album that show cases Wynton’s ability with classical music and I wholeheartedly recommend it to anyone; even just if you’re not really into classical music. Wynton is a magician with the trumpet and his talents are on full display with this record. Thankfully the open EL-8s were able to keep up with this very demanding recording. The quickness and openness of the EL-8’s drivers are on full display with this album. It never falls behind the recording and each note and player are crisply defined in the sound stage. The treble is outstanding. With some “brighter” headphones, the trumpet can come off as strident and lend itself to listener fatigue; thankfully the EL-8s continue in the natural sound tradition that Audeze has pioneered. The full spectrum is there, but never over taxing on one’s eardrum. There is a bit more treble and glare than with the LCD-X; nor as refined, but overall the EL-8s manage to paint a very realistic mental image of the stage with all the players in perfect proportion. The imaging is both wide and deep and compares to that of the LCD-X very admirably (although I still give the nod to the LCD-X here, but not by much).
Regardless of my source / amplifier, the open EL-8s sounded glorious. I certainly would not be intimidated if you were just planning to drive them from your portable player as they will reward you regardless of what you’re plugging them into. However, I did find that with better amplification and a better source, the EL-8s did scale appropriately and continued to improve. Considering the price point, the open EL-8s are going to be my “go to” recommendation for a pair of open-backed headphones in the sub $900 market. They hit on all cylinders regardless of the musical genre I threw at them (from rock to metal, to jazz and finally to classical) and the pure enjoyment that they brought me competed well beyond their humble price tag. The build quality is outstanding and the comfort level has been brought to a whole new level by Audeze. Using them for hours on end was never an issue for me. These are definitely a fantastic pair of open headphones and if you’re in the market for a natural sounding pair of headphones that competes with many US$1000+ top of the line headphones, look no further than the open EL-8s!

REVIREW SUMMARY:T he new Audeze is one of the most musical headphones I have heard to date. It stands up to high benchmark set by the LCD line and exceeds expectations with its top quality build, rich mids and organic realism.... With planars like Audezez LCD range the amplification field is almost wide open (you can still drive the LCD-4 from a phone in a pinch) and with that brings more options and new combinations to enjoy at a somewhat more value-driven pricepoint. A headphone is the final (and actual sound producing) element in any given personal audio rig, and is arguably the most important one. While flagship pricing continues to rise in the market, against some vantage points, the proposal of a $4k LCD can still be considered a value to those who can afford it. It is one of the most appealing and impressive pair of headphones I have ever formally reviewed. Highly recommended.
EXTENDED REVIEW: Even though headphone manufacturer Audeze has only been around for a relatively short period of time the company has managed to create an outstanding history with the personal audio community. Their flagship piece has always been born out of the LCD line, starting with the LCD-2 that quickly grew in popularity after its initial release. Subsequent releases featured the same progressive numerical namesake and formulaic pricing.
We now find ourselves on the precipice of a 4th iteration and the cost to play has risen along with ride to a flagship-worthy pricepoint of approximately $4k. At this range the competition starts to move slowly away from the Sennheiser dynamic driver heads-of-state and into the once-exclusive realm of Stax electrostatic technology. The only other real outliers that are unaccounted for is the $5k Abyss that has rested in the market for a few years and the new HiFiMAN HE-1000 ($3k) both of which utilize planar magnetic technology.
The headphone comes packaged in a “professional travel case” that sheds off the impracticalities of fancy wood displays for a secure and well-cushioned vessel for transport. Roughly the same size as the LCD-3 travel case, a concerned owner can even secure the top shut with an external suitcase lock. Inside the box, you will find a padded custom-fit lining and a detachable single ended ¼ inch to dual 4 pin mini XLR cable. This time around, the cable included with my review sample was slightly further away from the standard run-of-the-mill wire included with the previous LCD’s and closer to an aftermarket high-end audiophile cable, complete with heavy rubber build and bright blue color.
The headphone itself retains much of the shape and feel of the “2” and “3” with a few noticeable updates. The grill has been updated with a more chrome appearance and the leather headband has been swapped out for a carbon fiber split-band suspension (which supplies the clamping pressure) with light leather cover that rests on your head. The LCD-4 has also retained much of the weight of the previous models, so this updated design is a welcome one. Even with this above average weight, the new flagship is comfortable wear. I found the clamping pressure to be absolutely perfect for my head, something that is surprisingly rare among many mainstream (and even some audiophile priced) personal audio products. The wide circular design allows for plenty of space for your ears and the padding is deep enough so your fleshy audio receptacles don’t touch the drivers inside when placed on your head. The LCD-4 feels like a solid high end product all around, built to last and produce some sweet high fidelity output.
The new reference headphone combines elements of the LCD-3’s long-tail upgrade “Fazor” with an entirely new driver assembly. The diaphragm is an oversized but super-thin nano grade material. Most of the weight for headphone is generated from a specialty neodymium magnet array which Audeze claims has the most power magnetic flux density in existence at 1.5 Tesla. Audeze has also lowered the impedance and the efficiency slightly from the LCD-3 and in execution takes a little extra turn of the knob to reach the same volume level. All that “extra” really pays off when you look at the results they are able to achieve with the output.
First things first, the LCD-4 is a technical and musical improvement over the LCD-3, which is quite an achievement all by itself. There have been some remote instances in this hobby where follow up products have failed to impress as well as their predecessors, but this is not one of those times. All the minimum check marks are accounted for, tight bass, extended highs, vibrant mids. Holistically, the headphone takes detail retrieval to a new level. But the devil is not only in the details, it’s also in the delivery. The LCD-4 sounds supremely natural and organic, which equates a few inches closer to loudspeaker-like listening than ever before. It gives more of that elusive out-of-head experience that peppers the high end of personal audio like a celebrity sighting in a C & D county. It may be a tricky experience to grasp on paper, but detail in some gear can make your music sound closer, as if your ear is closer to the source and can hear every nuance. The magic of the LCD-4’s execution is that it addresses detail in proper form, but yet somehow manages to place the soundstage further away from your sensory receptors, which provides some experiential relief of sorts from the on-head, on-ear delivery of the device’s up-close-and-personal nature.
One thing planar magnetic headphones rarely struggle with is bass slam. Punch and quick impact comes easy for LCD-4 as well. It manages to deliver some of best low end sound available, while never compromising by relying on fluff or inflated response curves. That last low end piece fits perfectly into the puzzle, extended beautifully down into the darkness without an awkward break or speed bump. Fans of the thump from an 808 won’t be disappointed with the delivery, but the speed and clarity give it a high-end appeal unique to a well-balanced presentation. The delivery is such that it almost tricks your brain into thinking that it can feel it. Pushed to the limits the headphone showed no signs of break up or strain from dance/dubstep tunes to the most overdone YouTube bass tracks on the interweb. Even bass frequency sweep tests maintained their composure well to the 20 Hz limit (the headphone is even rated down to 5Hz on the company website).
The mids of the LCD-4 offer perhaps its greatest departure from the LCD-3. While the little brother is no slouch when it comes to accuracy and decisiveness, the LCD-4 pushes tonal texture just a bit further without a compromise to transparency. The strings from Serenade in G Major, K. 525 from the Pantatone SACD Sampler felt even more realistic and true-to-life, as if the listener can more clearly picture the bow upon the strings of each instrument individually. Even though the track doesn’t share a studio-isolated stereo image (with compartmentalized placement) the LCD-4 made it very easy to “see” each instrument through the wall of sound. The 4 even made it possible to discern the creaking of stage chairs from within the recording.
The quantity of treble is not that unlike the LCD-3, which may stir the pot a bit when it comes to the audiophile hive mind, but has always been right on target to this reviewer’s ears. The quality of said quantity projects a hearty yet tactful presence out from the middle to the ether above. The LCD-4 is a very easy headphone to listen to that takes a successful cue from the mids and delivers smooth, lifelike and non-fatiguing high frequency response that is exactly where it needs to be within the mix.
The new Audeze is one of the most musical headphones I have heard to date. It stands up to high benchmark set by the LCD line and exceeds expectations with its top quality build, rich mids and organic realism. As with many expensive purchases “is it worth it” should be heavily influenced by the amount of disposable income an individual has to spend on extraneous hobbies like high-end audio. I will offer this advice however, if you have $2k to spend on headphones the LCD-3 is a must for an audition. The same now holds true for the $4k mark. As electrostatic headphones sit right now, they often seem to hold a sound that is unique to its technology, and that tech often requires a larger investment to drive it. With planars the amplification field is almost wide open (you can still drive the LCD-4 from a phone in a pinch) and with that brings more options and new combinations to enjoy at a somewhat more value-driven pricepoint. A headphone is the final (and actual sound producing) element in any given personal audio rig, and is arguably the most important one. While flagship pricing continues to rise in the market, against some vantage points, the proposal of a $4k LCD can still be considered a value to those who can afford it. It is one of the most appealing and impressive pair of headphones I have ever formally reviewed. Highly recommended.
Audeze was kind enough to sit down and answer a few questions about the LCD-4 and its creation, below are the responses from our Q and A with Audeze’s CEO Sankar Thiagasamudram.
What were the goals in terms of technicalities for the LCD-4?
Audeze always looks to make the best product possible and the LCD-4 features our Double-Fluxor implementation of our custom-cut magnets that develop an astonishing 1.5 Tesla of magnetic flux, along with the thinnest nano-scale diaphragms imaginable.
Did you have a “target” sound signature you were shooting for during development?
Over the years Audeze has developed a house curve that works best with our planar magnetic technology. Our goal is to continue and improve the Audeze house sound. We’ve done years of research on impulse response and resolution, how people perceive sound, and other parameters giving rise to amazing tonal balance and accurate imaging.
Was the LCD-4 imagined as a progression from the LCD-3 or a completely different animal altogether?
The LCD-4 is a progression in design of the LCD Collection. Audeze is always improving, always concentrating on comfort, leading edge technology and the best sound available. But in terms of manufacturing and materials science, we’re talking it to a completely different level. We had to invent new ways to measuring the thickness of the diaphragm during manufacture. The Fluxor magnets took us quite some time to develop and again we had to invent new ways to manufacture them.
Do you have a recommended amplifier (or amplification design) that you feel pairs well the LCD-4?
Audeze recommends the 6W The King Headphone Amplifier of course (available soon) or any other high-performance headphone amplifier with enough power to drive it like our Deckard DAC/Headphone Amp.
The included detachable cable with the LCD-4 looks (and feels) like a significant departure from the previous stock wires included with the LCD line. Can you provide some more fine details as to its construction?
Audeze is like Switzerland when it comes to cable, we’re neutral and leave cabling up to our customers. However, we have a limited supply of very rare and special cables that ship with the LCD-4. They were created by audio legend Lee Weiland of Locus Design, and feature a special cryogenic process and proprietary cable design. When the supply is exhausted we’ll move to another quality supplier.
The weight of the LCD-4 doesn’t depart far from the heft of the LCD-3, did you have any significant design considerations or priorities that influenced the overall weight in of the new flagship?
Most of the weight comes from the custom-cut Double Fluxor Magnet arrays that achieve an astounding 1.5 Tesla magnetic flux. But the new carbon fiber headband is specially designed for maximum comfort and will eventually be available as an extra-cost upgrade/retrofit for the entire LCD Collection.
Will the LCD-5 cost US$8k?
All we’re saying right now is that we’re taking cars in trade.
Do you have any parting comments on the LCD-4 for our readers?
We call the LCD-4 limited production because they’re very difficult to manufacture. For example, each diaphragm actually takes a full two weeks to make! There’s no way we can put together even 20 units per month so it is possible that there could be some delay to deliveries.

Mids - more forward voiced than some of my headphones which are probably a little recessed. Vocals (male and female) and acoustics are spellbinding. ..... Overdriven guitars without additional distortion and lightning quick response to some really complex harmonies. .....They do have more extention but they are not bright. They have an almost ribbon feel to their top end which is crisp and airy but never bright or overbearing.
Bass - everyone knows that these headphones can do bass, but they do more than bass, they flesh out the texture within bass and respond to complex bass rhythms without muddying the lower mids. There is no bass hump ......the LCD3 reproduce a very real , almost palpable bass which some headphones just don't manage to portray acurately.
When I first heard the LCD2 , I thought "this is it" , this is what all the orthodynamic / planar magnetic followers have been looking for - "tactile" music that was both rich and organic, smooth vocals that pull you in and very responsive. "How could this possibly get any better!" well , it just did. How do I know? Tyll said so ( and he never lies. come to think of it , he doesn't drink, never swears and only eats vegans )

SUMMARY: the iSine10 is a success in that it delivers a new experience and makes the best out of the inconvenience Apple created by removing the headphone jack. Planar bass used to require a 100mm diaphragm; the iSine10 packs most of the experience into a case slightly larger than a quarter. Some enthusiasts attempt to emulate their home audio experience by attaching “portable” DACs and amplifiers to their phones with rubber bands; Audeze has shown that the same can be achieved by some tiny inline electronics in the headphone cable. We think that headphone enthusiasts value function over form, and we have no problem dishing out praise for innovation.
Innovative as it may be, the iSine10 is not a go-everywhere do-everything headphone. It’s fun to use outdoors, but does not isolate from ambient noise and may not stay in place unless without the over-ear guides. The iSine10 sounds great at home, but many will reach for full-size cans for longer listening sessions.
iSine10’s packaging and included accessories got us off to an encouraging start. Included in the box are a ballistic nylon case, three sizes of wide-bore silicone tips, four plastic ear guides, and two sizes of silicone “Earlocks,” (developed in collaboration with tactical gear company Surefire). The display case doubles as way to securely store the headphones and wind the cables inside the carrying case — a nice touch for protection of an admittedly pricey portable. Unlike the original Sine, the iSine10 includes both analog and Lightning audio cables as part of the standard purchase. The cables are flat and unsleeved, which makes them resistant to tangling but also a bit unruly in use.
We had some minor issues with the iSine’s ergonomics. Where most in-ears are small, rounded, and seat inside the concha, these driver housings are large, hexagonal, and stick out from the head by a few millimetres. The iSine10 is surprisingly light, but its long sound channels give the driver housings leverage to pull downwards, out of the ear. Though there is an engineering reason for the length of the sound channels – they house conical wave guides designed to improve various characteristics of the iSine’s sound – we found that it was not practical to use the iSine10 without some kind of ear support. This is especially true when using the Cipher cable, due to the added weight of the pod which houses that DAC and amplifier.
The included over-ear guides are the most secure way to wear the iSine10, but they didn’t work for us. The semi-rigid plastic hooks had just slightly too short of a rise and too steep of an angle relative to the iSine10’s housing to fit comfortably on our ears. We had better results with the flexible Earlocks – these were far more comfortable than the over-ear hooks, but we found that some regular cleaning was necessary to remove skin oils that made them slip out of the concha. Audeze includes two pairs of the plastic over-ear guides, but they’re the same size; from our perspective, it seems like a missed opportunity not to have included two different sizes. Getting the iSine10 to fit was a bit tricky during our testing, but we won’t call it a deal breaker – this is not the first time we’ve had difficulty fitting an IEM; the comfort of any in-ear can depend on the user’s individual anatomy.
When fit properly, the iSine10 is a unique experience. The silicone tips do not isolate like a traditional IEM, but instead seem to “concentrate” sound in the ear. The open-back design lets plenty of ambient sound in, but also provides for a wider soundstage and better imaging than we’ve ever heard in an IEM. Sound leaks out of the back of the iSine10 as well – not as much as some over-ear open back headphones, but it’s undeniably audible when played at high volumes in quiet environments. Regardless of whether you think the iSine10’s sound signature is for you, we think that this miniaturized open-back experience alone is worth a test drive.
The iSine10’s sound signature is difficult to pin down because it sounds different, depending on whether the analog cable or the Cipher cable is used. We listened to this headphone in a wide range of configurations, including a powerful tube amp, desktop solid state amp, a portable solid state amp, directly out of the iPhone’s headphone adapter, and using the Cipher cable. We listened to the iSine10 alongside a wide range of other headphones, including dynamic drivers and planars, open-back and closed-back, and IEMs. We put them up against cheaper portables and flagship cans, including Audeze’s own LCD-2 and LCD-3. With all this context, we found that the iSine10 is at once two completely different headphones. Depending on what you use to drive them, the iSine10 can be an interesting headphone that falls a bit short of its price tag, or it can be comparable to some of the best headphones on the market.
Our first week with the iSine10 was spent almost exclusively with the analog cable. As a planar magnetic headphone, the iSine10 responds well to amplification, but may be too sensitive for the high gain setting on some amplifiers. Over analog, we heard a warm sound signature that was at best “relaxed” and at worst “veiled.” This is not to say that the iSine10 wasn’t technically competent – we heard great bass extension and punch with all of the open-back soundstage and imaging that we think makes this headphone unique. Still, the recessed treble presents a somewhat congested atmosphere even compared to the famously warm sound of the Audeze LCD-2. Not yet having heard the Cipher cable, it’s a sound that we adjusted to and came to enjoy; this warmth makes for easy, low-fatigue listening, even though perhaps t can’t match the no-compromise quality of the LCD-3 / LCD-4.
If the iSine10 was “relaxed” over analog, it woke up with the Cipher Lightning cable. Like the Sine and EL-8 Ti, the Cipher cable drives the iSine10 substantially better than an iPhone headphone jack or the Lightning-to-3.5mm adapter. However, unlike its predecessors, the iSine’s Cipher cable presented a very different sound compared to the analog cable, even with amplification. All the best qualities of the analog sound remained, but the “veil” was lifted. A substantially boosted (or, no longer recessed) treble gives the effect of greater detail; this was drastic enough that we were initially concerned that there might be a nasty treble spike, but we soon found that this was just a more balanced sound signature than the dark presentation over analog. Having spent substantial time with both, we think that the Cipher cable is the best way to experience the iSine10.
What is the Cipher cable doing, and why? In our previous Audeze reviews we guessed that the better sound was simply due to more amplification, but Audeze has offered a more interesting explanation: the laws of physics make it impossible to design a headphone that sounds exactly as the designers intended in all situations. Even the most expensive headphones have peaks or dips in their sound that make them not ideal for some users. With the Cipher cable, however, Audeze can “bake in” DSP settings that can adjust the iSine10’s sound to the Audeze house sound. With DAC, DSP, and amplifier controlled, the Cipher cable can consistently output sound that matches Audeze’s original intent. With the Audeze app, users can further customize the sound.
.The iSine10 is a headphone clearly made by engineers, not a marketing team. Its looks are polarizing and one size does not (yet) fit all, but every apparent oddity is explained by the technology Audeze developed for this headphone. The iSine10 is a success in that it delivers a new experience and makes the best out of the inconvenience Apple created by removing the headphone jack. Planar bass used to require a 100mm diaphragm; the iSine10 packs most of the experience into a case slightly larger than a quarter. Some enthusiasts attempt to emulate their home audio experience by attaching “portable” DACs and amplifiers to their phones with rubber bands; Audeze has shown that the same can be achieved by some tiny inline electronics in the headphone cable. We think that headphone enthusiasts value function over form, and we have no problem dishing out praise for innovation.
Innovative as it may be, the iSine10 is not a go-everywhere do-everything headphone. It’s fun to use outdoors, but does not isolate from ambient noise and may not stay in place unless without the over-ear guides. The iSine10 sounds great at home, but many will reach for full-size cans for longer listening sessions.
Perhaps the best case for the iSine10 is as a portable audiophile experience — it’s a punchy planar magnetic sensitive enough to be driven by a phone and small enough to carry in a pocket, though it requires the Cipher Lightning cable to sound its absolute best.
“A joy for those seeking clarity, detail and an intimate relationship with the music.”
“The LCD-3's natural timbre, especially throughout the midrange, was a thing of beauty and one that is hard to go without once experienced.”
“Speaking of über-performance, the Audeze LCD-3 is quite possibly the best headphone ever ... Starting with the bass, the impact and detail is simply otherworldly ... Midrange performance is similarly stellar, with hints of bloom, but never unnatural, never exaggerated ... We were both simply floored by the LCD-3's physicality”
“They don’t really look like other headphones, and in many ways, they don’t sound like other headphones. No, they sound much, much better ... The word that comes to mind as I listen to the LCD-3s is 'realism.' ... There are some cases where spending more gets you more, and LCD-3s are an example of that.”
“I have never heard a set of headphones that got even remotely close to the sound of live music the way this one does and ...if you want the very best, get the LCD-3s.”
“From the butter-soft leather, to the gorgeous wood earcups, they exude luxury in a way most headphones don’t ... The Audeze LCD-XC’s are exquisitely well built and offer incredible performance ... Those two things define a good luxury item.”
A couple of weeks ago, Audeze surprised audiophiles and stuck huge planar magnetic drivers into its new alien-looking iSINE series. I was able to try out the ‘entry-level’ model, the iSINE 10 for about 30 minutes. In short: they sound like no IEMs (in-ear monitors) I’ve heard before.
That’s probably because they’re designed like no IEM before; the earphones are basically just funnels to direct sound from the nearly-full-size 20mm drivers directly into your ears.
For reference, IEMs normally use drivers 10mm or smaller, and while bigger isn’t always better, it works in Audeze’s favor here. Moreover, they’re planar magnetic drivers, which is supposed to translate into greater clarity and less distortion over standard ‘dynamic’ drivers (you can read a longer explanation of the tech here).
Most of the headphones remain outside of you ear, with the included earhooks keeping them in place. Despite their size, they’re deceptively light. I found them completely comfortable in about half an hour of listening, though you’re mileage may vary.
To keep the headphones light and the drivers properly vented, the iSine 10 forgo anything like a traditional in-ear headphone design for a webbed pattern seemingly designed by peter parker. I thought they press images looked pretty ridiculous, but they definitely look much better while worn in person.
Back to the sound: they best way to describe them is that they sound like something in between a high quality headphone and IEM. The iSine 10 have that clarity and intimacy you expect from good IEMs, but seemed to be able to throw sound as far out as smaller headphones that sit outside the ear.
They have that typical easy-to-listen-to Audeze frequency response with refined, but impactful bass. There was ample of treble presence – perhaps bordering on sibilant for some, but mostly just bright with good sparkle.
On the other hand, bass had some of the most ‘kick’ I’ve heard from IEMs, perhaps because of a combination of driver size and venting. The kick drums in Paramore’s Ain’t it Fun were realistically assertive, and true to Audeze’s claims, I didn’t notice any distortion even at the highest volumes.
They were easy to drive out of the LGV20 I’m in the process of reviewing, as well as out of the lightning cable I tried it with, although I couldn’t tell a difference in the time I spent trying. Perhaps it would be more apparent with a less audiophile-oriented phone (I noticed a difference when reviewing the on-ear Audeze Sine).
Though my time listening to them was short, I came away impressed. That’s not always easy for expensive audio products, which you often need to spend several hours or days listening to before you can really acclimate to them and appreciate their sound, but the iSine’s technology is so different from anything out there that the benefits become pretty obvious.
When much of the world is focusing on wireless audio and software-based enhancements, it’s nice to see you can still innovate with sheer sound quality too. Stay tuned for a full review when we get final units.
SUMMARY: I was able to run through my usual set of test tracks on Tidal, checking out the realism of vocals, acoustic instruments, and some good old bass-pumping EDM. The bass was brutal when it needed to be, and the voices came through sounding natural and real.
Audeze, the boutique audiophile brand responsible for some of the best planar magnetic headphones in the world, has done what many might have thought impossible and shrunken its technology to fit into an in-ear design. The result is the imposing, alien-looking thing you see before you: the Audeze iSine 10. It’s basically a 30mm planar magnetic headphone with a funnel to channel its sound into your ear.
As much as I’ve enjoyed Audeze’s high-end over-the-ear offerings over the years, I was skeptical about the wisdom of the in-ear iSine — but then I was quickly dissuaded by listening to the new headphones. The iSine 10 sound phenomenal, even inside the noisy IFA hall dedicated to audio equipment. Their soundstage is broad, their imaging’s precise, and their range extension, from deep sub-bass to high end treble, is outstanding. Overcoming the din around me, these headphones got loud using only the power of my Galaxy Note 7.
DON'T BE DAUNTED BY THE SIZE AND TECH, THE ISINES CAN BE POWERED BY A PHONE EASILY
Audeze sells the iSine with two cables in the box: one terminating on a regular 3.5mm jack and the other plugging into Apple’s Lightning port and also incorporating Audeze’s Cipher digital-to-analog converter and amplifier. Both the Cipher-amped iSine 10 and the pair plugging into my Note sounded terrific. I can already say, with a high degree of confidence, that Audeze has justified its oversized, outlandish design with extremely high sound quality. The $399 price point is a highly competitive spot for entry-level audiophile gear, and Audeze has asserted its credentials very nicely. But the company’s ambitions are grander than that still — Audeze tells me it’s a little worried that it underpriced the iSines, fearing that audiophiles wouldn’t take them seriously as a competitor to the very best in-ear headphones in the world.
Beside the iPhone-friendly version, Audeze will offer alternative options of the iSine 10 with specific cables for connecting to an Oculus Rift or an HTC Vive. Both of those will cost the same as the iOS variant, so it’s really a matter of what you favor most. There will also be an iSine 20, with a longer voice coil and a touch of extra resolution.
THE SOUND IS TYPICAL AUDEZE: CLEAN, BALANCED, DYNAMIC, AND EXCITING
The iSine aren’t without any compromises, of course. For one thing, they offer precious little noise isolation. The 3D-printed prototype I tested today had glorious sound, but offered mediocre fit. Not uncomfortable, just awkward to wear. Audeze offers Comply foam tips along with the usual silicone options, but the company admits that even in the best case scenario, you’ll hear plenty of exterior noise. On the other hand, these headphones don’t leak out much of your music at all.
In my 10-minute listen of the Sine, I was able to run through my usual set of test tracks on Tidal, checking out the realism of vocals, acoustic instruments, and some good old bass-pumping EDM. The bass was brutal when it needed to be, and the voices came through sounding natural and real. IFA is obviously a suboptimal testing environment, but the quality of the iSine feels just as obvious from even a brief listen.
The iSine 10 and iSine 20 will be available from the end of October, with their final design opting for a matte black finish rather than the present glossy look. On the evidence of my first time with them, these are going to be another win for Audeze, looking and sounding like a truly unique pair of headphones.

GOOD STUFF:
- Unparalleled purity of sound for the price
- Light yet durable construction
- iPhone-friendly Lightning cable option
VERGE RATING 9.3/10
It’s not often that you see a new pair of headphones that upsets the basic taxonomy of personal audio gear, but Audeze’s new iSine series is precisely that. The iSINE 20 that I’m reviewing today are ostensibly in-ear headphones, but they also use planar magnetic technology from over-ear cans, and they’re roughly the size of on-ear models. So they’re the ultimate hybrid, and their alien appearance certainly speaks to their uniqueness. What has me really excited about the iSines, however, is that they don’t just look out of this world, they sound like it, too.
Let’s get the basics out of the way first: the iSine 20s cost $549 with a regular detachable cable or $599 with an additional Cipher cable that provides a Lightning connection for iOS devices and a built-in 24-bit DAC and amplifier. My review is based on the experience of listening to them without the extra Lightning jazz, because that’s the fairest way to judge the performance of the headphones themselves.
The process of getting set up with the iSines is... well, it’s a process. You have to discard all your usual expectations of easily portable in-ear headphones, because that’s not what these are. The vast protrusions emerging from the iSines house a 30mm (1.2-inch) planar magnetic diaphragm, which is basically an ultra-thin sheet that dances back and forth, generating sound waves that are then funneled into your ear. There’s no getting around the bulk of such a large sound driver, and Audeze hasn’t really figured out a design that makes the iSines easy to strap to the sides of your face.
In the box, you get three sets of almost identically sized silicone tips, one shirt clip, a cleaning tool, and a 128MB USB drive with the iSine user guide. Two sets of over-ear hooks are provided, but I find myself most comfortable with the alternative plastic inserts that fit inside the ear cavity to stabilise each headphone. The over-ear stuff eventually makes my ears hurt, whereas using the headphones without anything holding them in place is an unstable proposition that leads to them falling out of my ears. With the plastic stabilisers, the iSine 20s rest lightly and easily inside the ear, and they can be worn for hours at a time, provided you don’t need to move around too much.
To minimize unwanted resonance resulting from reflections within the housing, the exterior of the iSines is semi-open — meaning they don’t insulate you from exterior noise very well and they leak some of their own sound out. Audeze provides a nice and rugged nylon case for these, but it’s quite bulky and doesn’t provide the same sort of impact or water ingress protection that a hard shell case would have done. Without the Cipher cable, you also don’t get an in-line mic.
Basically, every practical advantage of in-ear headphones is missing from these in-ear headphones. So why bother?
The answer is easy: these are endgame headphones. Every audiophile will tell you that headphones are a deep and dark rabbit hole — one where every step is an accelerating descent into a mad obsession with minimizing distortion, perfecting frequency response, and realizing the most faithful sound possible. What if you could sidestep all of that? Skip the struggle, expense, and time investment of learning all about audio and just buy the headphones that you know have nailed it. I could offer you some examples that guarantee that, like the Focal Utopia, but they weigh about as much as a modern laptop and cost several times more.
The Audeze iSine 20 are expensive and unwieldy by the standards of in-ear headphones, but they’re exactly the opposite when judged against other, truly high-fidelity headphones. If you want soundstage — the sensation of music and sound surrounding you; the feeling of distance, depth, and separation between the various instruments and sound sources — the iSines have it in abundance. They’re capable of incredible subtlety, projecting sounds so quiet and far away as to make me question where they were coming from. And these headphones are just as spectacular at high volume levels, where every note is full, convincing, and distortion-free. As far as human (or at least my) hearing is concerned, Audeze’s claim of "zero distortion" with the iSine 20 is a fully legitimate one. Their sound is faultless.
There are many technically impressive headphones out there that are guilty of sounding, frankly, boring. The Oppo PM3s, which also use planar magnetic tech like the iSines, are the perfect example of that. These are better. Audeze’s own on-ear Sines and over-ear EL-8s are also surpassed, in my judgment, by their weird-looking younger sibling: the 20s are that extra bit purer and more realistic, and their bass feels fuller, warmer, and more satisfying that the EL-8s can produce.
Good headphones are full of contradictions: the moment you expand the soundstage, you reduce the intimacy of a performance; when you add an extra kick of bass to bring dynamism in, vocals are pushed back; and amped-up treble frequencies give you the greatest sense of detail and airiness, but are also the most fatiguing to listen to. Audeze’s newest headphones balance all those spinning plates in a way that pleases both the critical listener and the casual music lover in me. They vastly outperform their price tag, high as it might be, and that’s what makes me willing to look past their impracticality.
If you want deep subterranean bass for artists like Aphex Twin or Feed Me, the iSines have it.
Steve Reich’s orchestral and instrumental works also sound amazing.
Rage Against the Machine’s eponymous album is revealed in all its detail and splendour.
And genre-defying musicians like Björk finally have a pair of headphones that’s just as comfortable straddling a wide variety of styles.
Recall the scene in The MATRIX where Cypher cuts into a fine steak, masticates thoughtfully, and decides to betray "all of the humanity" for what he knows is the synthetic illusion of a "juicy and delicious" meal. Headphones are kind of like that: most of them are like video game recreations of a musical performance, while the best among them approach a Matrix-like realism that's beguiling and enchanting. I think the iSine 20s are in the latter category.
These are not the headphones for every person or every occasion. But listening to them is, in itself, an occasion of the sort that everyone can appreciate.
For those on a smaller budget, Audeze also has the cheaper/smaller iSINE10, which aren't quite as life-altering as the 20s, but still deliver an expansive and satisfying sound that is light years ahead of most things you can plug into your ears. At CES this year, Audeze also introduced the iSINE-VR, which is the 10, but with cabling specifically tailored for virtual reality headsets.

Conclusions - the Audeze iSine 10’s are a home run for Audeze — but they’re not for everyone. We like how they look given the fact that they need to be as big as they are, and they’re generally comfortable despite their size. Not only that, but they sound great despite a few frequency bumps along the way.
While the Audeze iSine 10’s unique approach makes them difficult to review, as there’s no other planar magnetic in-ears to compare them to, Audeze is innovating and that’s an important consideration. Do you need these? Probably not. But those looking
So what’s so special about the iSine 10’s? Well, they’re planar-magnetic — and in-ears. In fact, the iSine line is the world’s first planar magnetic in-ear headphone. But are they worth it? Yes, they are.
Design
The first thing to notice about these headphones is their design, and boy is it an interesting one. The “world first” label is complimented by an alien design that does away with conventional in-ear designs that we’ve seen over the years. That’s not necessarily a bad thing — just a different thing.
Of course, there’s a reason they have the design that they do. Because of the way planar magnetic headphones work, shrinking down the technology into super-thin 30mm drivers is already a feat of engineering, and as such, considering the fact that they need to be at least slightly large, these in-ears actually look pretty good. They boast an all-black look with a cover that looks kind of reminiscent of Spiderman.
You can kind of tell that the larger outside basically just funnels sound into something that fits inside of your ear, but that’s not necessarily a bad thing — the funnel design fits with the rest of the in-ear pretty well.
In the box, you’ll get the in-ears themselves, a carry case, two detachable cables (one 3.5mm cable and one Lightning cable), a few different earhook styles, and a few different eartips. You’ll also get a sleek-looking USB that contains the user manual — a very high tech way to deliver the manual.
The whole package is put together beautifully, and it’s clear that the people at Audeze want the iSine 10’s to be a seamless experience from start to finish. The box is nicely packaged, everything is easy to understand, and the case is clearly of the highest quality — although it’s not a hard case, so don’t put too much weight on it with your precious headphones inside.
In general, while we would have liked a somewhat smaller in-ear, technological limitations mean that we won’t get it yet, but knowing that the Audeze iSine 10’s look absolutely awesome.
Comfort
You might assume that the Audeze iSine 10’s are a little uncomfortable because of their size, but they’re a lot more comfortable than many other in-ears we’ve tried.
First up, it’s true that the headphones are a little heavy for in-ears, but that’s to be expected. You’ll definitely want to use the ear hooks with the iSine 10’s — otherwise you’ll most likely face them falling out regularly.
When it comes to fit, the eartips actually aren’t that bad. They’re certainly big, which can get slightly uncomfortable after long periods of listening time, but not abnormally so, and not much more than other in-ear headphones.
Sound
Ah, the all-important sound — something that can make or break a pair of headphones.
First up, the Audeze iSine 10’s are open-back, meaning that they let plenty of outside sound in and let plenty of what you’re listening to out. Now, we’re a little torn on this. The open design certainly helps improve the sound quite a bit, but the point of in-ears and earbuds is portability — to take out on the road. You definitely don’t want to be hearing the sound of the bus on your way to work. If you’re buying headphones for home use, then you may as well buy the full-sized Audeze Sine headphones, which we reviewed and absolutely loved.
In any case, the fact is that the Audeze iSine 10’s are open-back, which is something to keep in mind.
The bass on the Audeze iSine 10’s is pretty solid, though we felt there was some super low bass lacking — which could be owed to their smaller size. Most will be happy with the bass offering despite that, but those who like really boosted bass might want to look elsewhere — these are a little more natural sounding.
Audeze iSine 10 Lightning
When it comes to the mids, it seems like there’s a slight boost in the lower mids, which gives the Audeze iSine 10’s a bit of warmth — which is kind of nice. The higher mids seem to have taken a slight hit because of the lower mids boost, but there are still plenty of high mids to go around.
Last but not least are the highs, and there are a good amount of highs here too. Like the bass, it seems as though there’s a slight roll off when we get into the really high frequencies, but most won’t notice that — vocals are still nice and clean while guitars still have plenty of bite.
Frequency ranges are important, but on the Audeze iSine 10’s it’s almost as if they aren’t. The first time we put them on was a weird experience — they sound like over-ear headphones. They sound wide, and open — which is likely owed to the open-back design. It’s an interesting feeling, and while we do have a bit of a hard time finding a use case for the iSine 10’s, we love that the tech makes something like this possible — and it’s exciting to think about the future of planar magnetic headphones.
Conclusions
The Audeze iSine 10’s are a home run for Audeze — but they’re not for everyone. We like how they look given the fact that they need to be as big as they are, and they’re generally comfortable despite their size. Not only that, but they sound great despite a few frequency bumps along the way.
While the Audeze iSine 10’s unique approach makes them difficult to review, as there’s no other planar magnetic in-ears to compare them to, Audeze is innovating and that’s an important consideration. Do you need these? Probably not. But those looking for a great-sounding and portable in-ear with an open design will love them.

SUMMARY: The King hides its royal title behind a clean, sober, workmanlike audio presentation. Which is good: that mute-spectator neutrality let it get out of the way of a wide range of headphones—and a wide range of musicians just trying to be themselves. It let cowboys sing ballads, Rasta fellas be 2 Tone rudies, cocktail crooners be faux seductive, and jazz guys with crocheted hats be serious hipster dudes. Peasant amps bowed down in the presence of The King, village folk called it "Your Majesty"—but to me, that sounds too patriarchal. I think we should call it The Monarch: The King played music with the authority of an absolute ruler
With headphones, I'm pretty much forced to listen—and that's a powerful thing. I never paid attention to lyrics: I thought lyrics were for girls. Now, with headphones, almost all I hear are the lyrics. I'm embarrassed that it's taken me this long to overcome my misplaced sexism, validate my anima, and embrace this essential aspect of musical content.
Note that I said lyrics, not words. I said lyrics because high-quality headphones put me close not only to the recorded sound of a singer's voice, but to the presence of that singer and his or her lyric-writing intentions. With headphones, the space between microphone and singer feels tangible: a mutually shared space. And that lets me feel closer not only to the singer's mouth, but to the long-gone pieces of paper the composer wrote the lyrics on.
Loudspeakers allow me go to the bathroom, check e-mail, and shift in and out of focus. In contrast, headphones literally hold my head and tether my body to the amplifier. Consequently, they keep my consciousness glued to the song and aware of its vibrating musical elements. Good 'phones do pace, rhythm, and timing (PRaT) easily and naturally, like a puppy chasing a tennis ball. They do texture, weight, and body (TWaB?) better than any coughing, tubercular minimonitor. Headphones pressurize the ears directly and continuously and with full force; a loudspeaker's energy diminishes exponentially as it travels from the cone to our ears. Headphones compel the mind and conduct music through the bones of the skull.
Audeze The King headphone amplifier
Stereophile's editor-in-chief, John Atkinson, politely asked, "Herb, how would you feel about reviewing Audeze's The King headphone amplifier?" I gave voice to my spiritual mantra: "Hell yes!" "You should use the Audeze LCD-4 headphones I just reviewed."
Have you ever seen a dog's face when he sees you pull a cocktail wiener from your pocket? That's how my mug looked when John said "LCD-4." I'd already tried these highly regarded 'phones a few times, but my reactions had been inconclusive. I was anxious to listen to them more intensely in my bunker, with my own music. How would the Audeze LCD-4s ($3995) compare with my reference LCD-Xes ($1695)—or with Focal's Utopia References ($3995), which I'd raved about in the October 2016 "Gramophone Dreams"?
Audeze's The King is named for its designer, Bascom H. King, high-end audio's never-aging, top-gun engineer, who has recently designed amplifiers for Constellation and PS Audio. A standalone headphone amplifier that can output 6W into 20 ohms, The King is moderately large (11.8" by 4.3" by 12.8") and heavy (19.8 lbs), but looks light and streamlined. Its circuit is a hybrid, using ECC88/6DJ8 dual-triode tubes for the input and MOSFETs for the output. Its output impedance is 0.3 ohm, its input impedance 10k ohms. The 5/8"-thick front panel features dual parallel ¼" output jacks and corresponding rows of flashing green power-meter lights that indicate, in dB, the sound pressure level of the specific headphones for which the user calibrates the output. (Just below the flashing lights, my review sample's display said: Calibrated for LCD-4.) On the rear panel are only an IEC inlet for the power cord and pairs of XLR and RCA jacks to accommodate The King's single, unbalanced analog input. The King's substantial machined-aluminum case sits on sturdy shock-absorbing feet.
By Candlelight:
Frequently, on my weekend dates, the romantic mood begins when I play one of my newly discovered "special" recordings for my partner, bb. She always listens with focused intensity, but, to my disappointment, never notices anything special about the sound of my ever-changing reference system.
After years of this, I played for her, through headphones, a recent album produced by David Chesky: Macy Gray's Stripped (LP, Chesky JD389). bb owns every Macy Gray CD, and was stunned by what this simple binaural recording and some good headphones were doing for her experience of Gray's music: "This sounds so real and unproduced. She is so close! . . . I can feel her connection with the band."
"Listen! Can you hear her following the lead of her guitar player?"
Slowly nodding her head and speaking a little too loudly, bb declared, "Now I get it! " She removed the headphones. "I understand now why that audio stuff you write about is so important. I have never experienced music this intimately!"
Later, bb and I zoned out together on the bed, listening again to Gray sing "Annabelle" through his-and-hers Audezes: respectively, the LCD-4s and LCD-Xes. Watching bb absorb satisfying, soulful Gray, I was reminded of the direct, intimate, dream-enhancing power of music—and of headphone amps with two front-panel output jacks. I also became aware of how radically different in sensitivity these two models are. When I set the volume to bb's preference with the LCD-Xes, I could barely hear Macy Gray through the LCD-4s.
The King hides its royal title behind a clean, sober, workmanlike audio presentation. Which is good: that mute-spectator neutrality let it get out of the way of a wide range of headphones—and a wide range of musicians just trying to be themselves. It let cowboys sing ballads, Rasta fellas be 2 Tone rudies, cocktail crooners be faux seductive, and jazz guys with crocheted hats be serious hipster dudes. Peasant amps bowed down in the presence of The King, village folk called it "Your Majesty"—but to me, that sounds too patriarchal. I think we should call it The Monarch: The King played music with the authority of an absolute ruler.
After I installed The King, I began re-auditioning all of my headphones—beginning with four LCD models from Audeze.
SUMMARY: I was treated to a big (as in deep + wide) soundstage, with linear and textured bass (as opposed to thick, one-note offerings) that was in the running for the very best-in-class. Driving the cans was the announced and soon-to-be-available fancy-face The King headphone amplifier, designed by prodigy Bascom King.
Now, this isn’t to say that the personal audio, or more properly, the headphone market (including the amps and other bits that feed them) was in some way deficient, but it was … ripe. A decade or more of big companies getting increasingly shoved aside in favor of upstarts that brought quality, innovation, and passion meant that the enthusiasts were pushing the envelopes. Perhaps unfortunately, that envelope was underdeveloped. Sound quality, as good as it was, was pretty mediocre. At best. At least, mediocre when compared to its much older and much more developed (even if it was, at the time of the Beats acquisition by Apple, much smaller) cousin, hi-fi. So, when I speculated that the hi-fi entrepreneur had a lot of room to pillage explore in matters head-fi, it was only to say that there was opportunity. For finesse. For subtlety. For the true artist working in glass and steel and wood.
Fast forward a few years. We have amplifiers marching toward $10k. Portable audio players that are tipping toward $4k. And headphones that are sliding past $5k. Regrettable, those prices. But that’s where personal audio is heading (and way past those markers, for sure). Why? Because there’s still a lot to do. That can be done. Personal audio is still way behind “traditional” two-channel hi-fi.
But now Audeze is making a move.
About 18 months or so ago, I got a clue that Audeze was going down-market. That their next offering, what was to become the EL8, would be their first serious foray into the sub-$1k market. And now, this year, with their new flagship, the LCD-4 ($3,995), Audeze is going in the other direction. Up. Waaaay up.
Audeze is killing it.
Now, a US$4k headphone is crazy-expensive, but it slots in right comfortably between offerings from HiFiMAN and Abyss. The fit-and-finish is the best-ever from Audeze, and the new tech — a super-fine/nano-scale membrane and massive 1.5 tesla magnets — read like missive from a tech-sheet dream world. 100Ω means a tube-friendly load. Those magnets mean speed. That membrane means detail. That finish means PUT-IT-ON-MY-HEAD.
So, at CanJam, I did.
I was treated to a big (as in deep + wide) soundstage, with linear and textured bass (as opposed to thick, one-note offerings) that was in the running for the very best-in-class. Driving the cans was the announced and soon-to-be-available fancy-face The King headphone amplifier, designed by prodigy Bascom King.
The King’s circuitry is very different from the typical complementary output topology; it uses the same polarity N-channel MOSFET outputs as these are more alike and complementary than N- and P-channel MOSFETs. Just before the output stage is a two-stage differential amplifier using a dual-triode tube for the input stage followed by a P-channel MOSFET differential driver stage. The driver stage supplies complementary drive to the N-channel output devices. Overall negative feedback is taken back to the input stage to include the input triode in the feedback loop. The circuit is DC-coupled from input to output and a servo control circuit keeps the output DC offset to within millivolts of zero. The overall symmetry of the circuitry eliminates most even-order harmonic distortion. The result is a low impedance, low distortion, wide frequency response output with immense musical transparency, a real emotional experience.
The amplifier is rated to 6 watts, which should be more than enough to drive everything currently on the market.
SUMMARY: Extremely fine resolution without ever becoming over-analytical. Clean bass even at high volumes. Despite their weight they are comfortable to wear.

EXTENDED REVIEW: The Audeze LCD-4, the American headphone manufacturer’s top model, looks kike a joint venture between the oddball inventor of the flux capacitor in “Back to the Future” and Serbian America physicist Nikola Tesla. Its price, meanwhile, is pure Cartier…
The price barrier for headphones was completely demolished when Sennheiser launched its near-€ 50,000 Orpheus, beside which the € 5,000 demanded for the Audeze LCD-4 is not really that shocking. Audeze (pronounced as though written by Homer) was founded in 2008 by Sankar Thiagasamudram and Alexander Rosson, along with busy NASA developer Pete Uka. Swiftly reinforced with the addition of Dagoslav Colich as technical director, the company was soon gaining international recognition with its series of remarkable headphones.
The LCD-4 is designed to invade the territory of the recent HE 1000 by Hifiman and the large Stax ’phones, and even the first encounter demands respect: the 680g weight demonstrates the solidity of the workmanship. Is it elegant? Well, that’s a matter of opinion, but to these eyes it’s spoiled by the numerous screws holding together the components. Functional chic, perhaps?
Audeze has developed a number of technical ideas to make the headphones “loud” and dynamic, not least of which is a possible record 1.5 Tesla of magnetic flux, achieved by a patented arrangement of magnets dubbed “dual fluxor”. The energy may not be quite enough to facilitate time travel à la Doc Brown, but Mr. Tesla, who gave his name to the standard unit of magnetic flux density, would presumably approve. A lot of work was also put into the headband in order to create something innovative, using a carbon band above the leather to combine the required ‘clamping force’ with comfort.
In addition, the open, circumaural earpieces contain extremely thin planar magnetic driver membranes, designed to set new standards for resolution and impulse accuracy as well as outstanding soundstage representation. As in the EL-8 model, this top model also uses ‘fazor’ technology, involving acoustical elements on both sides of the magnets: these have a positive impact on the frequency response as well as the high range resolution while at the same time reducing distortion and, according to the designers, delivering that improved spatial reproduction (a traditional weakness of headphones). It’s all about complement the positive characteristics of the ultra light membranes, drive right across their surface, and the strong neodymium-magnet ‘motors’.
The massive, asymmetrical ear cushions are very pleasant to wear but, as usual, you have to look for a second to find which is the left and which the right side. The labels are very subtly hidden on the inside of the headband in matte engraved print, to the point that – as with most of its competitors – the chances of finding the channels in the dark tend towards zero (though that asymmetry helps!).
Plus points include the high-quality plug-in cables included in the set, each about 2m long and offering a choice of stereo jacks or XLR format , and stored along with the headphones in a practical, cushioned plastic travel case.
It’s good news that these technical fireworks are completely made in the USA and not some discount country: while we don’t feel this justifies its astronomical price, it at least helps us understand a little bit when comparing it to the pricing of its competitors.
In terms of sound, things got off to a strong start: the power with which the LCD-4 blasted sounds by Leontyne Price, Jan Garbarek, or Monty Alexander into the ears of the listener felt matchless. While these 100 Ohm headphones were a bit quieter than the Hifiman 1000, when used with the Malvalve reference headphone amp they were able to depict dynamic subtleties we’d never heard before. The bass was clean and detailed, although unable to distinguish itself from that of our reference headphones even after a few days of break-in.
It was interesting how the Audeze spatial reproduction: the sound wasn’t quite as clearly ordered as it would be with good speakers, but it did separate quite astonishingly from the confines of the earpieces and project itself into a wide and cleanly encircled space, sounding clearly less diffuse than with our other reference headphones. In terms of sound, Garbarek’s saxophones, especially the soprano on “All that is beautiful” (how true!), had a touch more presence than usual, but this was without distortion or harshness.
These are headphones delivering a thrilling musical experience, meaning you’ll want to keep on listening: it’s fortunate, then, that they’re comfortable to wear over extended periods – despite their not inconsiderable weight.

SUMMARY: Trying to be level headed The Audeze LCDi4s might not be the beginning of your personal audio journey, but they can certainly be the end. Offering such a high degree of tonal neutrality and dynamic range, they can also make for an incredible reference by which to judge any other components you might consider adding or upgrading.
These are certainly this headphone curmudgeon’s favorite headphones, by a considerable margin. Be ready to plunk down your credit card. You won’t be able to un-experience these. The LCDi4s are crazy money, but they are crazy good. Consider yourself warned!
EXTENDED REVIEW: I must admit, for those of you new to our readership, I’m not a headphone guy. But like the World’s Most Interesting Man, when I do listen to headphones, I listen to Audeze. My journey began with their original LCD-2s, that for me turned my world around and adjusted my attitude. These were finally some headphones that sounded like a great pair of speakers. And they had bass; real bass. Though you’ll never get that punch you in the gut” feel, produced by a big pair of speakers. The extended, defined bass response of the Audeze phones is tough to ignore.
As much as I do not like head - phones, on a boat or a goat, I like inear phones even less. Other than the $4,000 Stereo Pravda’s which is my current favourite, IEMs have been pretty disappointing.
Doing some background reading on the LCDi4 headphones you see here; I noticed that Audeze works with Design - works, who just happen to work with BMW (and I’m a big fan of BMW) and they also have a financing option for the LCDi4s. I’m paying less than that to lease my new BMW i3. That there were high expectations going in, would be putting it mildly.
Minor grousing
While the LCDi4s come in a lovely, luxurious case, the USB stick owners’ manual doesn’t clearly explain to someone uninitiated with headphones just how to use those damn ear things, that help hold these relatively large IEMs on your ears. The cable supplied looks to be of high quality, but it’s way too short and presumptuous that you’d want to use headphones this awesome (letting the cat out of the bag here) only with an amplifier limited to a mini jack output. A quick video would be helpful, and a 1/8" to ¼" adapter should be in the box, along with another six feet of cable.
Resisting the urge to sneak a quick listen during the break-in period, the LCDi4s were plugged into an iPhone 5 and looped on a long Tidal playlist to make sure they were broken in. Rustling a proper adapter out of the toolbox, serious listening began in earnest with the Pass HPA-1, the PrimaLuna HP Integrated and a freshly re-capped Marantz 2245 just for giggles.
Beep beep, yeah!
The best part of my job is when, after nearly 40 years of being a hi-fi enthusiast and the last 15 listening for a living, is to have my world turned upside down completely. The Audeze LCDi4s are worth every penny asked. Where my other favourites, the Stereo Pravda phones sound like someone put my Focal Sopra no.3s in a shrink machine, the LCDi4s sound like someone put a brand new pair of original Quad 57s and put them in a shrink machine, so you can insert them in your ears. Should you have the chance to audition these phones, make sure you are relaxed, centred and in your happy place. Make sure they are plugged into a fantastic source and headphone amplifier too. Yes, they sound good with a laptop, phone, pad or modest amp, but if you want to fully experience what the LCDi4s are capable of, they need an exceptional source
These phones are the pinnacle of personal listening. If you have a mega two channel hi-fi system that you’d like to take with you wherever you go, the Audeze LCDi4 phones are your ticket to ride. The key word is refinement. These phones offer refinement across the entire audio spectrum that is unmatched anywhere else in the world of portable listening. These phones offer a level of refinement I’ve only heard through few great two channel systems
Where so many headphones produce an overblown, overextended sonic field between your ears, which usually has way too much sonic contrast and saturation, the LCDi4s merely unfold the music as a great two channel system does. Imaging is spot on, and eyes closed, if not for the lack of pants rattling that goes with speakers, the spatial relationships are correct, feeling like there are a pair of large, high-quality speakers in front of me. The longer I listen, the more I swear I hear stuff bounce off the walls in my listening room, but I’m not.
The level of minute detail revealed by the LCDi4s is so enthralling, you will be going back to your favourite recordings to give your ears a tune up. Should you not have a mega two channel system to listen to sans phones, the LCDi4s will open up a new world of listening pleasure. Think of them as a six figure hi-fi system that fits in your pocket.
Further listening While numerous examples of tracks can be listed, the key here is that music sounds correct through the LCDi4s. Tonal, dynamic and spatial cues are so good, within 15 seconds of listening, you completely forget you are listening to headphones. The level of distortion is so low, as it is in a great planar magnetic or ESL speaker, whether you are listening to acoustic instruments, vocalists or crunchy guitars through a wall of Marshall amps, it sounds like music, not like music through electronics, scrunched into some tiny earpieces. This is the way music sounds through a great hifi system.
You simply must hear these to believe them. If like me, the only thing that’s put you off about your full sized, over ear Audeze phones is their size and weight, this is the variation on the theme you’ve been waiting for. Much as I love my LCD-2s, I can only keep those big things on my head for so long. Good as they are, they still lack the ultimate level of refinement and transparency that the LCDi4 does.
Like a pair of fine loudspeakers, the better your system, the better the LCDi4s will render your music collection. Jacked into my reference system, they were not out of place using the dCS Rossini DAC and clock for digital tracks and the Grand Prix Audio Monaco 2.0 turntable we recently re - viewed, via the Pass XS Phono. Chan - netting nearly $150,000 worth of source components through the Pass HPA-1 is a visceral experience, to say the least.
Trying to be level headed The Audeze LCDi4s might not be the beginning of your personal audio journey, but they can certainly be the end. Offering such a high degree of tonal neutrality and dynamic range, they can also make for an incredible reference by which to judge any other components you might consider adding or upgrading.
These are certainly this headphone curmudgeon’s favorite headphones, by a considerable margin. Be ready to plunk down your credit card. You won’t be able to un-experience these. The LCDi4s are crazy money, but they are crazy good. Consider yourself warned.
