AKG K 702 Black
European leaders in recording studio headphones give us the AKG K702, a top-of-the-line full-size audiophile and professional model with precise articulation, an engrossing "front-row" musical presentation and complete accuracy across the audio spectrum. Like the brother-model AKG K701, the K702 are nowhere near their acoustic potential right out of the box; patience and a long 'break-in' period [allow 300-hours!] gets rewarded with a headful of beauteous, pristine tunes. World-class reference headphones rivaling the performance of some four-figure cans but at a fraction of the price. Black color with detachable cord.

AKG Acoustics in Austria has brought their considerable audio engineering skills into sharp focus on their high-end dynamic headphone designs and produced an astonishingly superb-sounding pair of cans in their flagship K701 and in this nearly-identical K702 model. The only differences between the two is color and the K702's handy 'quick-detach' cord, which makes it a breeze to replace or upgrade later. As headphone lovers know, getting it absolutely right at this demanding level of reference-grade audio performance is tough and the K702 gets pretty darn near perfection. These headphones deliver a truly dynamic and texturally punchy sound, articulate and clear over the entire audio spectrum. Precise musical detail connoisseurs should appreciate the clean punch and tightly focused bottom-end control of these headphones. Classical and acoustic music afficionados will likewise love the fact that the dynamic control moves right on up the frequency range to distinctly articulate every finger pluck and rosin-on-gut string texture present in the sound mix. The soundstage image is deeply expansive and simply layered. Really about the only negative thing that we can say about these headphones is that those who like a very laid-back, mellow-sounding, or heavy bass presentation might want to look elsewhere since the K702 are very highly refined audiophile headphones that deliver analytical detail with a liquid immediacy that demands your full attention. And... oh!... what a lovely musical demand it is! For folks looking to approximate the sonic performance of $1,000 headphones, we think the AKG K702 can get you there at a fraction of the price.
As mentioned, the major difference between the K701-White and K702-Black is the K702 has a detachable headphone cable while the K701 cord is a fixed 'hard-wired' cable. Both of these basically identical AKG cans offer a number of unique features that create a dramatic improvement over previous AKG 'best-of-category' headphones. Their dynamic range extension and clarity of musical detail and texture is directly improved by a revolutionary proprietary AKG Varimotion diaphragm that is designed to provide smoother pistonic motion and excellent acoustic resonance control. Further, AKG's revolutionary flat-wound voice coil design allows for greater concentrations of the magnetic field within the coil, thus driving the element diaphragm with more authority to deliver a cleaner, faster and ultra-articulate response.
Our own HeadRoom experiences with the AKG K702 echoes the widely held assumption that it requires an extensive chunk of burn-in time to 'open up' sonically and perform at its best, so assume a MINIMUM 300 hours of play-time before the full pleasure of these cans is realized. The soft fabric 'ergonomically-perfect' earcup cushions are a soft velour material -- very comfortable -- and are also designed to correctly angle the drivers precisely at the ear for a more spatially correct listening experience. The K702's easily detachable cord links to the headphones using a 3-pin 'mini-XLR' plug cable system featuring an extremely secure connection and ease of cable replacement should it ever become needed. High-end after-market AUDIOPHILE cords are also available. The headphone cord terminates to a 1/8" [3.5mm] jack with a 'screw-type' 1/4" [6.3mm] plug adapter provided. We love the K702's deep blue-black color scheme, which is understated and sleek. We also think most listeners will enjoy how amazingly comfortable these full-size headphones feel on the head with their well-designed, albeit slightly oversize ergonomics.
For portable listeners using the AKG K702 with iPod, iPad, mp3 players and computers, a dedicated headphone amp of some sort is simply a must for maximized audio performance due to the headphone's low sensitivity, despite its fairly efficient 62 Ohm impedance. Our entry HeadRoom 'Mobile Line' portable headphone amps ($99-$159usd) will do the trick nicely but the more accurate, robust and dynamically-quick HeadRoom 'Micro' or Desktop Amp come well-recommended for this superb headphone.
For dedicated AKG K702 listeners, HeadRoom recommends investing in an upgraded K702 replacement headphone cord from Cardas Audio. Cardas headphone cords are renown for improving dynamic range quickness, soundstage imaging depth & 'spatiality' and maximizing overall musical detail resolution. It's certainly worth trying for audiophiles looking to make their beloved K702 perform at the very top of their acoustic game. Remember, our 30-day 'no questions asked' HeadRoom return period guarantees you'll love what you hear!

Recommend Product: Yes
Pros: Great sound
Cons: Uncomfortable, flimsy cord
One, the foam padding around the can is fairly firm, and if I center the cans on my ears, it digs into the sensitive point just behind the angle of my jaw. If I move the padding up to ride on bone instead, the sound quality is slightly, but perceptibly, diminished. This is clearly personal, and depending on the size of your head, this could still be a great, comfortable choice.
Two, I can't wear glasses with these. This is not unique to full size headphones, and I don't blame the 702s for this, but remember if you wear glasses, and they don't fit flush to your head, these will push them out of line with your vision.
On the subject of sound, these are brilliant. So amazing that I deeply, sincerely wish I could wear them. I generally listen to classical music, and these handle everything from Arvo Part's "Alina" to Peter Hurford's amazing rendition of Bach's "Passacaglia and Fugue in E minor" with aplomb. The sound I get from these is every bit as enjoyable as that I get from my full size stereo.
The cord feels a bit thin and flimsy, certainly less substantial than I expected at this price point.
I would recommend these, but with reservation, and only with the caveat that you try them for comfort before settling with them.

Pros: Relatively comfortable, very precise detailed sound
I was thinking about getting a pair of Sennheiser HD 600's when I impulsively purchased a pair of used AKG K 702's at a very reasonable price. In music I am very familiar with, I heard instruments, percussion, and harmonies that previously escaped me or just weren't as audible as they are with the AKG. With either the HP 1000's or the HD 580's, I could hear what was newly audible, but not with the same presence and immediacy of the K 702's. It's a bit like being in the first few rows of seats at a baseball game instead of in a good seat in the upper deck. The HD 580's in particular have, to my ears, a more unified sound but there's more sizzle with the 702's. I'm not giving up the HD 580's; I'm fascinated by the differences among the very good headphones that now have, but I listen mostly with the AKG's. Given the price of the K702's they are a great value. I'm saving up for one of the Cardas Fat Pipe cords.
One final thought, The AKG need some power to drive them. My Centrance DacPort is barely sufficient on some recordings; my HeadRoom Bithead has enough power. But, I can't imagine trying to use the 702's without a good amp.
