Product Description

The iSINE20 is one step up from the iSINE10 featuring an even longer Uniforce voice-coil that covers the ultra-thin diaphragm to a greater extent, enabling better control and responsiveness for better bass, clarity, and improved imaging. Zero distortion sound means you’ll feel closer to your music. Add the included Lightning cable with DSP and there’s no other in-ear headphone that even comes close to its performance.

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 iSINE20s 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. Their sound is faultless.” THE VERGE

The hybrid design produces a soundstage more akin to a holographic projection around your head, as if you’re listening to top-notch speakers in some sort of personalized, augmented reality. There really is nothing quite like the soundstage the iSine 20 create, and it’s a stirring experience right from the start. You’ll almost swear you hear the music echoing around you, while the outside world is filtered stealthily into your custom sonic lair." DIGITAL TRENDS

Simply put, there's nothing else on the market like the Audeze iSINE series. These headphones are truly one-of-a-kind, in basically every way." APPLE INSIDER

"They’re remarkably clear and crisp ... like looking through a window that you’ve just wiped clean for the first time." THE WALL STREET JOURNAL

Audeze iSINE20 Planar Magnetic In-Ear Headphones

iSINE20 in-ear headphone

The superiority of Planar Magnetic drivers

Unlike conventional headphones, Audeze’s planar drivers use a very, very thin film (much thinner than Saran Wrap for example) to move the air that produces sound. Because this material has such low mass compared to conventional headphone drivers, it moves extremely fast, thus giving much better transient response/impulse response. This means percussive sounds like the snare drum, strumming acoustic guitar, popping strings on a bass (and car crashes!), all sound much more accurate and lifelike. Additionally, Audeze headphones’ Step Response test is always positive - just like real world sounds, which is not always true of conventional headphones.

So conventional drivers not only have more moving mass (the cone, the surround, the voice coil, the spider, and the glue holding everything together), they also have more distortion than Audeze’s planar drivers. In fact, our drivers may have as little as 1/10 the distortion of other headphones.

All of this means more accurate, and therefore, more realistic sound.

ABOUT AUDEZE

iSINE20 In-Ear headphones

Audeze started in 2008 in a garage (of course!) when its founders came across a revolutionary flexible circuit material developed for NASA. Realizing this could be a great advance in planar magnetic technology, they first started to make pro audio PA speakers, but dropped this project and started making headphones – the LCD-1.

Taking this first headphone to the Rocky Mountain Audio Fest, it was a tremendous hit, and that success launched the company. Hanging on that garage wall was the 2001 Space Odyssey poster, and that inspired the company’s name. The founders wanted a name that had something to do with a “journey through audio,” so Odyssey would be perfect, and that’s how the name Audeze (pronounced “odyssey”) was born.

AUDEZE'S PLANAR MAGNETIC TECHNOLOGY

Driver technology call out image

Acoustically engineered for accuracy

Audeze’s innovative planar magnetic technology delivers clear and accurate sound that reveals everything on the recording.

Diaphragms thinner than a human hair

We use space-age materials in an ultra thin diaphragm four times larger than typical headphones for fast response times, dramatically reduced distortion, higher resolution and improved imaging.

Near zero distortion

Magnet arrays deliver a uniform driving force across the entire diaphragm for near zero distortion.

Fluxor magnets

Our patented Fluxor magnet design has almost 2x the efficiency of other magnets, giving the iSINE a more dynamic impact.

5 Stars
OMG these are excellent, comparing to my reference Shure 846 and others, ZERO negatives!
Have had these less than 24 hours at this writing, and these are flat out excellent. I have written many high-end audio reviews on Amazon, for speakers, and open & closed back headphones. Current equipment is Oppo Planars, Shure 846, and Aurisonics and Beyer T5P.Sound: Treble, mids and bass...tonally accurate, lively, well extended across the spectrum.Fit for me: clear hooks and out of the box tips are fine; using shirt clip to support mike /controls on a loop on my upper chest. Sensation or feel of the actual earphones is light, effortless and unaware i'm wearing them!What I like most: These are most like my KEF LS50W, and my Oppo open back planners. Zero detectable distortion; i can increase the volume, and exponentially just have more music and fullness, no noise, sibilance or ear fatigue. Soundstage very broad, open airy, great instrument placement. Artists used to test, Katherine Jenkins, Amber Rubarth Binaurals, Noah Wall "Down Home Blues", Stevie Wonder , piano concerto no 1, 1812 Overture and the Eagles (last 4 Flac on Onkyo Player.) Other than any obvious drawback using these say for a sweaty workout, or in noisy environments, these are a Joy to listen to. While open backs have their drawbacks, they help somewhat for me, whom may feel claustrophobic listening to closed headphones or IEMs over time.At any rate out of the box, these compare to anything I have in the $700-1400 price range. Excellent for Classical to Rock, and high pitched female vocals, which are difficult not to sound fatiguing and sibilant in the presence of any distortion. Using on an iPhone 7, straight up with Cipher cable at factory EQ!These are likely my go to earphones on the move, which is most of the time, love them and highly recommend!UPDATE 8_16; 1 WEEK LATER...I noticed about 3 days of owning it seemed like they had lost mid range to bass. So experimented with tips, and tried the second tip up with the ridges, sound was rich and full, so ; and they sounded great but after an hour or so, hurt my ears. So i tried the second smooth silicone up from the smallest, and now wearing them a week, and the sound remains full, great base, excellent vocals, soundstage etc. and they are very comfortable even after hours. Walked at our mall, and they sounded rich and full, despite being able to hear prominent ambient sounds. Originally I had the shirt clip, below the controls on the earphone cord, and it bounced and was annoying, so i placed it about 11/2 inches above the controller, and it is fine.
