What Bose?!?!
by kongkenguru on May 15, 2009
Pros: Exceptional sound quality
Exceptional quality build (as well as warranty)
Cons: hmmmm.. really tried to nail at least 1 con- however- its just not possible.
I could always say it doesnt have built in rechargeable battery, but I actually like the AAA batt solution better as they'r avail anywhere you might run out of battery...
Summary: Absolutely blows competition away. I have had the BOSE Quiet Comfort 3 for about a year and a half, and during this time the cord has snapped twice, the connection ...

Summary: Absolutely blows competition away. I have had the BOSE Quiet Comfort 3 for about a year and a half, and during this time the cord has snapped twice, the connection on the ear cap has broken off ( connected with 3 pathetic small screws and low quality palstic). The BOSE do however have a better fit and comfort than the KOSS, but when it comes to sound and overall quality- the KOSS is unprecedented. And including the warrant- these headphones the perfect choice. KOSS could easily have charged the double or even tripple and my opinion would still be the same.

- Manufacturer: Koss Corp.
- Part number: QZ900
- Description: The QZ/900 is the addition to the Koss Quiet Zone line and adds a new level of performance and comfort. The electronics package inside each Koss QZ/900 is designed to monitor outside noise received through specifically mounted microphones in each ear cup. Once this incoming noise can be analyzed, the Koss QZ/900 circuit introduces a sound wave which is 180 degrees out of phase with the incoming signal. The result is what engineer's term "zero earth" at the point of the eardrum. This means that most low frequency distractions from an airplane, lawn mower, fan, or even the din of an office can dramatically reduced. Once the QZ/900 reduces the outside noise, the sound of Koss takes center stage. Deep rich lows and sparkling highs in a stereophone you'll want to take along everywhere. In fact the noise canceling ability is so good in the QZ/900 that you'll find less need to turn up the volume and overdrive the tiny amplifier in your portable electronics. This means greater efficiency, less distortion and all the excitement of a live performance. The QZ/900 operates with or without its active noise canceling circuit engaged. A handy removable cord features an in line volume control and one standard AAA battery provides approximately 50 hours of active noise cancellation.
