Koss QZ50 Active Noise Reduction

Description:
QZ50 Active Noise Reduction Stereophone. A generation of music lovers is coping with noisy world. Anyone particularly those who regularly travel and are exposed to repetitive sound can find peace in this new noise reduction stereophone.The QZ50 creates an invisible shield between the listener and the droning sounds of the world by stopping low frequency noise before it reaches the ears. The tiny microphones embedded in the earcups send the incoming low frequency noise and send it to a processor also located in the earcups.The processor in turn generates a mirror image in the form of a signal that acts as an anti-wave that is 180 degrees out of phase with the outside low frequency. The two waves counteract each other resulting in a reduction of the low frequency repetitive noise. Designed as a compact all inclusive stereophone unit the QZ50 features a behind-the-head headband design for maximum comfort and wearer flexibility during long listening periods. Closed ear cushions provide additional isolation from ambient sound and retain the bass frequencies for an enjoyable listening experience. The QZ50 features iron boron magnet structures and oxygen free copper voice coils for a frequency response of 30-20000 Hz and clean clear sound reproduction. Using one AAA battery the QZ50 delivers approximately 200 hours of battery life.Ideal for reducing jet engine noise during airline travel the QZ50 is also a perfect accessory wherever ambient noise is excessive. Koss Corporation produces additional active and passive noise reduction stereophones including the QZ2000 QZPro QZ99 and QZ5.More noise cancelling headphones at Minidisc
