Extremely comfortable with well balanced, neutral sound.......2007-06-07
Working in a cubicle, I listen to music nearly all day, every day. I have been using the AKG k601s for the last fourteen months or so, plugged into the headphone jack of a component size CD player. I listen to a wide variety of music including electronic, classical, and post-rock.
COMFORT.
With this experience, I can confidently report these are the most comfortable headphones I have ever worn. The are very light on your head, and apply most of their pressure to the area around your ears. The soft, well padded cups fit entirely over my average sized ears, with room to spare--even with eyeglasses. The leather headband pressed on the top of my head a little when new, but that slight discomfort disappeared quickly. Again, I cannot think of a better testament to the comfort of these cans than the fact that I repeatedly wear them for four- or five-hour stretches. I also own a pair of Sennheiser HD595 headphones that I can compare the k601s with. The Sennheisers also are very comfortable, but the ear cups are not as large, and may present problems for folks with larger than average ears.
SOUND.
I have been very pleased with the sound of the k601s. When I first got them, I immediately rediscovered my CD collection, hearing details and nuances I had never noticed before. I'm not talking about a minor difference, but an incredible, eye-popping experience. If you have never heard high-end headphones before, you will hear songs like you've never them before. This is my favorite aspect of the k601s. Whenever I buy a recording now, I always prefer to hear it first over these headphones, rather than my home system. As far as neutrality, I believe they are fairly uncolored. I have not seen anything from AKG, but an impressive response curve can be viewed on www.headphone.com, which, by the way, is a great merchant. Since the drivers are so close to the listener's ears, headphones typically have reduced output in the higher frequencies (i.e. treble) and higher output in the lower frequencies (i.e. bass). The curve for the k601 follows this philosophy, and to my ears, the cans sound fairly balanced across the frequency range. The bass may be a little thin, though the notes are reproduced and audible--just not with large amounts of sound pressure. Again compared with the Sennheiser HD595s that I recently acquired for home listening, the k601s have a noticeably diminished lower frequency output. I'm not sure how I feel about that, perhaps because I have become accustomed to the leaner k601s, and the Sennheisers bass seems more prominent than its higher frequencies. Many folks recommend a long break-in period for the k601s, and I suspect it has to do with getting used to the bass output. They are not heavy hitters as far as bass goes, so hip hop fans probably will be disappointed. I don't know, but suspect--based on reviews and the response curves--that the bass output is one area in which an upgrade to the top-of-the-line k701s would be justified.
DURABILITY.
Using the k601s every day in an office setting has exposed them to a fair degree of wear and tear. I have found them to be very durable, even after repeatedly dropping them onto the floor and running over the cord with my chair. The ear pads have come off, but they just click back on. I returned the cans for warranty service after I started hearing distortion: where the cord connects to the left side had become audible loose, though not visually. This was probably because of misuse on my part (allowing the cord to get caught and having it pull taught on the earpiece at times), but AKG re-corded the headphones for free. The cord itself is fairly thick and well insulated. It has withstood numerous roll-overs.
FUNCTIONALITY.
The headphones have an average impedance overall, less efficient than smaller supra-aura `phones, and less efficient than other circum-aura, open-backed cans like the Seenheiser HD-650s. You will not necessarily need a dedicated headphone amplifier with the k601s. The headphone jack on my Marantz CD5001 cd player drives them very well. I also have had success listening to internet radio, plugging the k601s directly into my desktop computer. I suspect, though, that an Ipod would not have enough voltage to drive these very well, and I doubt you'd want to wear the bulky k601s on the subway or bus. The unique design of these headphones may or may not strike your fancy, but it achieves comfort, as I've already described. I purchased a pair of HD595s, however, for home use because the k601s aren't as suitable for wearing while laying on the couch with your head on a pillow. I must also mention that I use these open-backed headphones in an office setting. Even though they are not a sealed design, I've found that very little sound leaks out at the volumes I listen to. I've confirmed this with my co-workers in the adjoining cubicles. Plus, I like being able to hear my telephone ring or know when someone has entered my cube. If active noise reduction is more important, however, you'll have to look elsewhere.
CONCLUSION.
At from two to three hundred dollars, the AKG k601s are top notch headphones from a well respected, science-based manufacturer with enormous R&D resources. I cannot imagine you will be disappointed with them after an extended listen, except perhaps if you value bass reproduction over everything else.

Portable players:
I recently have begun using these headphones with a Creative Zen MP3 player at my desk. Not expecting enough voltage, I was really surprised to hear how good the MP3s (compressed .WMA files at the highest resolution) sound through these cans without additional amplification. I'm not hearing much distortion at a reasonable volume. I suspect extra power would only result in a fuller sound, but I don't see the need for it right now. The advantage of the MP3 player, to me, is the jukebox shuffling--not audiophile sound quality. If you want random, uninterrupted playback of your favorite songs at your desk, then I am not aware of a lighter, more comfortable pair of headphones to keep your listening private.
Head-to-head:
After further comparison with the Sennheiser HD595s, I really have to say these two sets of headphones both offer seriously detailed and refined sound reproduction. Purchasing either gives you a lot of "speaker" for the money. How much would comparable loudspeakers costs? From what I've auditioned, you'd have to spend at least a grand, and that would be for mini-monitors! The greater bass response of the Sennheisers is the most obvious difference. If you mostly listen to music with drums and guitars (i.e., rock), then the HD595s may sound most familiar to you. However, I suspect you'll find the k601s will reveal more detail in vocals and the upper frequency ranges, something to which you may become addicted. I'm not saying the AKGs are more accurate--just that it's definitely easier to hear the mid and upper frequencies with them. Indeed, the Sennheisers to my ears sometimes seem too heavy on the bass. Each could be said to color the sound: the HD595s by overemphasizing the lower frequencies, and the k601s by failing to reproduce them at the recorded decibel level. So, pick your coloration preference of bass omission or bass emphasis. Or, if you can afford it, spend more on the top of the line model in either company's catalog and see if better neutrality is achieved.

Looking for hi-fidelity sound that doesn't take up any floor or shelf space? The new W3 provides the kind of transparent, neutral, wide-range sound you expect from Axiom, without any of the compromises that plague other in-wall speakers. Other in-walls rely on the wall cavity to tune the bass output, resulting in a speaker whose performance varies from wall to wall and room to room. Additionally, the drivers' rear output produces distorted sound in the neighboring rooms.
Overcoming these drawbacks, the W3 features a fully integrated enclosure that recesses into the wall, combined with an attractive exterior baffle portion that keeps the speaker's woofer and tweeter well away from the sound-degrading effects of the wall's front surface. The speaker ports are cleverly hidden at the base of the outer baffle.
The W3 on-wall/in-wall hybrid speaker preserves the sonic clarity of its bookshelf equivalent, the M3, and adds a slim profile that is a perfect complement to today's modern low-profile plasma and LCD TV screens. The large 6 1/2-inch aluminum cone woofer produces satisfying bass output in medium to small rooms.
A supplied self-clamping frame anchors the speaker firmly to the wall when the screws are tightened. The series is available in a variety of attractively-finished front baffles to suit any decor.

Not great.......2007-06-23
This broke a little while after I got it. I ended up buying one that snaps into a foam keychain from Target and I'm much happier with that purchase.
