eh.. [Posted on 2006-06-28] i just bought these at radio shack for $50. the fit is ok but they pinch a bit after a while. the sound is pretty dissapointing. the noise cancellation feature doesn't do a lot and they sound quite muddy. the only thing i do like about them is their size. i will probably return them.
Horrible! [Posted on 2007-01-16] The sound is mediocre to subpar and the fit is painful. The noise cancelation depends on a skull-crushing fit to be effective. I got these as a gift and I'm certain I wouldn't have purchased them on my own (without random and extremely manipulative council or, winning them with a 28% interest credit card).
The AAA battery-powered noise cancellation is a pain in the arse because it is easy to leave it switched on after you take them off. Thus, going through batteries quickly. There is a red LED incicator light but, it is on the right speaker/driver shell and still easy for this dumb bell to notice it on. If the batteries are weak, the sound gets really crappy with extreme bass distortion. Also, after about 10 mins of play (with even new batteries), volume loss is apparent.
This isn't ideal for sports activities so I do not understand why there is such a short cable lead of only about 3 feet(??).
All-in-all, kinda crappy.

Waste of time [Posted on 2007-02-19] While these headphones sounded decent to me, they became too much of a headache after a couple months.
The plastic >:( part that holds one of the speakers to the headstrap broke I guess because I pulled them too far apart to fit over my head...
Koss replaced them, and the same exact thing happened a month later and it was a brand new pair. I found a piece of metal to brace the crack so it would stay straight and that has worked fine. Apparently they cheaped out on a very important part here.
And last night, they just stopped working all together. I tried them on different music players with no success.
Save yourself the annoyance that I went through with these headphones. Oh and I never even bothered with the noise cancellation feature. It just sounded odd when in use.
best value for money [Posted on 2007-04-10] QZ-Pro performs as advertised. Noise cancellation is excellent and you can use the earphone for your mp3 player as well as for the audio the airplane has in the seats. There is one small problem though, the battery placement. It's not easy putting in the battery. Also, the picture advertised is black, but the headphone comes in chrome.
koss qz-pro [Posted on 2007-06-12] Sound lacks richness in high frequencies.
Spring-loaded ear pieces: they crunch your head, they are too strong.
Music sounds like in a concert hall, but you are sitting too far back.
Noice Cancellation is like magic! A+ on that.
