Feature:
No features needed.

Quality:
Seems to be constructed well. They're simple, look good and have a great design for fitting anysize head automatically.

Value:
Best value in what you get. My next favourite pair (Denon AHD-550) are a lot more.

Desirability:
They look good hanging beside the stereo.

Sound:
I use them purely for listening to music. They do justice to everyone from Michael W Smith's "Freedom" to Kurt Bestor's "Innovators" to Secret Garden to "Best Blue Note Album in the World". I've tried about a dozen different headphones ranging up to $150 Sennheiser's. These have the best all around frequency range that you can actually hear coupled with being distinct enough to hear stage noise of breathing flutes etc. - and for the price it's nearly unbelievable.

Support:
Haven't needed support.

Overall:
I expect to get 10 years of normal use out of these...or more. If they got crushed by my Unimog today I'd replace them with the same ones, no question.

Feature:
Noise attenuation? well im not sure exactly what this means but im pretty sure these phones don't do it very well, like a sieve both ways I'd have said.

Quality:
Seems fairly robust, I feel that if i were to jump on it fairly hard I could write it off in one go, but if you don't walk on them too often then they feel like could last a fair few years.

Value:
Rather good value for money I think overall

Desirability:
Well, I don't think I look too silly wearing them, but come on man... earphones don't pull chicks.

Sound:
I havent't used many headphones, but I can confirm that these do give a sound pleasing to my ears and don't seem to distort at loud volumes.

Support:
Haven't had the pleasure as yet

Overall:
Should keep me occupied for a few years yet, they'll probably meet their ultimate demise under an amp at some point.

Feature:
Plug them in, listen. What more features could you ask for. ;)

Quality:
The reason why I love the K55's is the build quality. I've had my pair for a number of years, I can't even remember how many. I break headphones that cost three-four times the K55's in a fraction of that time. I've rolled over the cord with my office-chair a number of times. They are actually so old now that the paddings are beginning to dry out, without them becoming uncomfortable to wear. And that's another thing, for me, this is simply the most comfortable headset I've ever owned or tested. I searched for the K55's to get an additional pair for the office, not to replace the pair that I already have, to me it's as good as new. The cord is comfortably long, so you won't have to get an extension cord, but it's pretty much useless for portable players.

Value:
I'm having a hard time imagining that the K55's can be beat at the $29.99-price listed on this site.

Desirability:
They're big, and not the best lookers, but comfortable to wear.

Sound:
The sound and sound quality is good, the headphones are relatively well shielded. Perhaps not the best for monitoring and production, but excellent for listening to music.

Support:
Never needed any.

Surprisingly good for a "value" headphone. Better translation up and down the frequency spectrum than what I was previously using (Fostex T-20s and T-40s). Only negative is the 1/8 miniplug to 1/4 plug adapter, which gets loose after long usage. Since these are sold as "studio" phones, IMHO, they should have the molded 1/4" plug only.

It's good for the money. But slogan on the box - "Turbo Bass" and "Unique Turbo Bass funktion" is a brazen lie. Shame on you AKG. By the way - this K-55 are very comfortable for long time using (I used it for in-door electro guitar playing trough the amp)

Feature:
It feels relatively comfortable. The design is similar to other AKG headphones (self-adjusting head band, one-sided cord, etc).

Quality:
Average quality made in Chian. I don't like the fact the ear pads are permanently glued to the headphone (but it's not like I would want to get replacement pads anyway!)

Desirability:
I don't want it!! Actually at the first sign of intermediate connection problem at the jack (the scratch noise, off and on connection), I threw it away, even though the rest of the phones were fine. I have no regrets. Normally, I would just replace the phone jack with a new one. So I don't want it that much.

Sound:
In short, the K-55 sounds pretty bad. I have a AKG K240M and have been very satisfied with it, so I thought I

Good sound, good price. The cups fit over the entire ear....very comfortable.

Feature:
None. It's all one piece, and the headband is too easy to stretch out and get it stuck.

Quality:
Junk. I was impressed at first.. cheap headphones with a decent sound. But after a couple months the sound no longer comes out of the right ear. The headband fits my head decently, and it isn't too uncomfortable. But it doesn't even fit bigger heads. The ear pads get uncomfortable very quickly.

Value:
If you need cheap headphones NOW, then yeah, go ahead and buy these. But you'll want to upgrade in a few weeks, or a month. Only buy these if you need a cheap, temporary solution.

Desirability:
No, not at all. I would only consider getting these again if I was in a bind and needed to buy a few pairs very fast, very cheap, and only to use for a day or two.

Sound:
They don't sound very good. But for $30 they sound alright.

Ease of Use:
Plug it in, and it works. Until a couple months later.. now sound only comes out of one ear.

Support:
I haven't contacted them. I'm not really sure I even want another pair, but I may call them tomorrow.

Overall:
Pretty junky. Save your $30, and invest in a better pair. Because you'll want a better pair after having these for a couple days.

Good Headphones @ a great price
