Active Noise Cancellation Headphones with Volume Control
QZ900
$249.99$275.00
Koss QZ900 noise-canceling headphones will create less reason to turn up the volume and overdrive the tiny amplifier in your portable electronics. This means greater efficiency, less distortion, deep rich lows, and sparkling highs.
Unlike most other noise-canceling headphones, QZ900s play music with or without the active noise canceling circuit engaged. A handy removable cord features in-line volume control, and one standard AAA battery provides approximately 50 hours of active noise cancellation.
