More Noise ADDITION than cancellation! Jan 04, 2006
By D. Fredriksen
"aworkingstiff"
I asked for, and received, these for Christmas. I tried them without the noise canceling feature enabled. They are closed-ear and do reduce ambient noise from the environment (about the same as any other closed-ear phones). I was very disappointed to find that when I turned on the noise cancellation, it actually INTRODUCED MORE noise. They apparently have poorly designed amplification circuitry and there is a signficant amount of hiss when the noise cancellation is turned on. I have not yet evaluated their ability to cancel low frequency sounds (like road and aircraft noise) but the high frequency hiss makes them unacceptable for listening to music with this feature turned on.
Bottom line: they are a little pricey for use as low end closed-ear headphones, which is their only suitability. Buy a pair of Sennheiser HD201's or HD202's for this purpose at half the price. If you want noise cancellation, buy something else.

 Horrible! Jan 16, 2007
By S. Parshley
"Cooked (pronounced like crooked)"
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.

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.

 best value for money Apr 10, 2007
By Francisco D. Villanueva
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.

Skip the QZ-Pros and Buy Something Better Jul 12, 2011
By Richard Eckert
I've had the Koss QZ-Pro headphones for several years and cannot recommend them to anyone. The noise cancellation is marginal at best and when turned on the noise cancellation introduces lots of annoying hiss.
My wife has a pair of Direct Sound Extreme Isolation EX-29s which although they cost more, are far superior to the QZ-Pro. The EX-29s are passive so they do not require batteries plus they block all outside noises, not just the low rumbling noises.
I recommend skipping the QZ-Pros and spending a little more to get a decent pair of noise cancelling headphones.
