Koss QZ50 Noise Reduction Headphones

Noise Reduction?

The Koss QZ50 Noise Reduction Headphones are a response to a modern problem. Headphone wearers now are forced to deal with ever more noisy environments. Anyone, but 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 pick up 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.

What About Comfort?

The Koss QZ50 headphones are so comfortable to wear that you'll hardly know that your wearing them. The Koss QZ50 features a behind-the-head headband design for maximum comfort and wearer flexibility during long listening periods.

What About Sound?

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 30-20,000 Hz and clean, clear sound reproduction.

Anything Else?

Using one "AAA" battery (which powers the noise reduction), the QZ50 headphones give approximately 200 hours of battery life.
