Product Description
The QZ900, latest addition to the Koss Quiet Zone line - adds a new level of performance and comfort. Designed to monitor outside noise received through specially mounted microphones in each ear cup. Koss QZ900 circuit introduces a sound wave which is 180° out of phase with the incoming signal. The result is "zero earth" at the point of the eardrum and dramatic reduction of most low frequency distractions, resulting in deep rich lows and sparkling highs, noise canceling ability so good you'll need less volume for greater efficiency and less distortion from overdriving the tiny amplifier in your portable electronics.

Customer Reviews
Average -- nothing special
Just got these the other day, and already have a few observations.
Pros:
- Like that they work with and without the noise cancellation feature
- Appear to be good quality, nice package and good case
Cons:
- Convenient battery placement, but over time you can already tell there will be problems with ear pad on right side (where battery is) will become loose and non-operational.

A good alternative to Bose QC-2
I bought the Koss QZ900 headphones, after a lot of research, as a lower cost alternative to the Bose QC-2 headphones. I've had a chance to compare them to both the QC-2 and QC-3.

Good Value
I did a lot of research on various noise canceling headphones and landed on the QZ900 for the following reasons: Over ear design, in-line volume control, price, previous experience with Koss headphones.
