Description
Let’s face it: listening to music on an airplane is almost impossible. Even if you crank the music up louder than the engines, chances are you’ll still miss most of the music and subject yourself to shrill, high frequencies that induce fatigue. The Koss Quiet Zone QZ/2000 headphones, or stereophones, as Koss calls them, are tailor-made for use in planes or other environments plagued by loud or intrusive background noise.
Using a sophisticated system of noise cancellation, the QZ/2000 headset significantly reduces the perceived noise level of static low-frequency sounds. In doing so, the headphones also cancel a portion of the music at those frequencies, but the net effect is unquestionably improved clarity in your music. The QZ/2000 works well for general noise dimming, even if you don’t intend to listen to anything. Just put them on, switch the noise cancellation on, and enjoy your quieter environment.
Sometimes the absence of one noise reveals another, previously unnoticed noise (usually a high-frequency tone), which can be distracting. But by and large, we found the QZ/2000 effective at reducing noise from air conditioners, freeway traffic, and even general office din. Most pleasing is the Quiet Zone effect on listening to music at low levels: with less environmental noise, music can be heard more cleanly and more fully at lower volumes, so it sounds better and is also safer.
As headphones, the Quiet Zone 2000s are decent, though not great–clearly, you’re paying for the noise reduction here. The ‘phones are mellow and full-bodied, if slightly muddy, with little in the way of high-frequency detail. This last factor also keeps any sense of harshness out of the program–not such a bad thing, given the strident nature of many headphones.
While the QZ/2000 claims to reduce high-frequency noise as well as low, we detected very little noise reduction in the bass range. But for general noise reduction and relaxing in-flight listening, the Quiet Zone QZ/2000 is just the ticket.

ADVERTISED AND A BIT MORE. VERY HIGH QUALITY AS IS
KNOWN WITH KOSS. I LIKE THE FIT OF THE UNIT OVER THE
EARS BUT NOT THE TOP. THEY USE CHEAP METAL THAT LAYS ON
THE HEAD AND THE WEIGHT OF THE UNIT PULLS DOWN ON THE TOP.
BUT WORKS EXCELLENT. THE BEST I HAVE TESTED. THEY LOOK ALOT
LIKE THE PORTAPRO'S BY KOSS AND MAY HAVE THE 50 MM DRIVERS ALSO.
FOR THE BASS IS THE SAME GOOD QUALITY.
HAPPY CAMPER
they fold up nicely and include a good travel bag. a pair of rechargable AA batteries in these lasts seemingly forever.
regardless, the foam cover on them has completely deteriorated and i can't find anywhere that sells a replacement. bad!
pick other headphones with a vynil or velvet liner rather than foam if you'll be using these a lot.
I hook the QZ-2000s up to my PDA, which I use as a jukebox, on cross-country flights. Noise reduction terrific, sound quality very good (but not quite Pro 4AA), battery life outstanding, reasonable price. Physical durability has not been horrible, but could be better. Outstanding mfr service after sale.
Man, I wish that they would create a similar unit with a mike on a mini-boom for telephone and computer VOIP use.
getting a 2nd set for my gf, and have had none of the sound
issues complained. Quite the opposite. I have tried several
sets of lower priced units, and found the noise (hiss) from
the electronics to be quite unacceptable. The 2000's have
no audible hiss or artifact noise whatsoever. While they don't
cancel all frequencies, I can now hear my laptop with about 1/4
the voulme level on a plane flight, which is why I bought them.
Overall, and excellent noise canceling system. And I don't
really think that perfect sound is available on a plane.
For what it's worth. :)
