Quite similar to Koss UR-20 but adding a handy in-line volume control, it's hard to believe Koss can make a full-sized closed-back headphone this substantial at this low price, but here it is -- the UR-29. Ideal for commercial applications or just inexpensive personal listening in any setting, the Koss 'Mix Master' UR-29 will isolate you from outside noise and carries Koss' sweet lifetime warranty. Great choice for classrooms, audio/computer labs, museums, doctors offices, dorm rooms, commuting, etc.

When the Koss UR-29 'Mix Master' headphones first arrived here, our HeadRoom geeks were quite excited. If Koss could deliver a totally decent $20 full-size sealed headphone with their famous UR-20 model, we wondered what would $30 bucks get us? Well, not much more it seems except a handy in-line volume control to eliminate klutzing with the volume levels on your audio player. But just getting this much relatively well-made plastic + electronics together remains a feat to marvel at considering the extremely low cost of these big durable cans. In fact, there exists few better-sounding headphones to be found at this crushingly low pricepoint. Thus, these are GREAT headphones for schools, museums, doctor's offices, computer labs or any other commercial headphone application -- or just for killer personal listening at a bargain budget. The volume control located right on cord may be a convenient plus for many users.

The Koss UR-29 Mix Master are quite rugged, sealed /closed-earcup headphones with easily cleaned 'pleather' full-size (circumaural) earpads and a nice cushy size-adjustable headband. The earcups are hinged, allowing the headphones to be folded up into a lumpy bundle for easy storage and transit. Other UR-29 Mix-Master features include that neat volume adjustment slider built into the cord and a good-looking, durable silver/black cosmetic finish. The non-detachable 8ft cord exits from the left earcup and terminates to an 1/8" (3.5mm) 'mini' plug. A full-size 1/4" plug adaptor is nicely included in the UR-29 packaging. The 100% 'Lifetime Warranty' from Koss-USA is uber-sweet too, so keep our HeadRoom "authorized Koss dealer" purchase receipt just in case!

Good sound, poor design.
Posted by Jon from Nashville, TN on 2011-06-26

Recommend Product: Yes
Pros: Balanced sound, comfortable
Cons: Sketchy build quality

These heaphones are really good for the price, but aren't incredibly well built or designed. They don't press on your ears or sides of your head at all, which makes them very comfortable, but you have to turn them up pretty loud and they don't reduce any noise at all. After 4 weeks of use the in-line volume control broke off, so I taped it over and phones still work fine (I didn't really use the volume control thing anyways). The last pair of Koss headphones I owned broke as well. So overall they are good in terms of sound, but if you're rough with hp's at all I wouldn't recommend them.

Audio-wise, the highs are quite smooth and the lows are pretty clear and not overpowering. You won't feel like you're missing any frequencies.

Homerun Christmas Present!
Posted by Dr. Daf from Tucker, GA on 2010-01-16

Recommend Product: Yes
Pros: Comfortable, pretty compact, precise sound quality
Cons: a little heavy

I bought these for my husband as part of his Christmas present this year. He wanted some really good headphones to use at the office. So these headphones, with their terrific quality, make him happy! He likes the volume control in line and the only comment was that the control is for both sides of the headphones. He has some hearing loss in one ear so it would be nice if it were adjustable in both sides. Very Happy!!!

Very Durable
Posted by ellebean from Cape Coral, Fl. on 2010-01-15

Recommend Product: Yes
Pros: Good Value

I now have two of these, one old and one new and I must say that I can't part with the old ones to break in the new ones. The old ones have duct tape on them but they still provide quality sound.
