Koss QZPro Noise-Reducing Headphones
The Koss Quiet Zone QZ Pro headphones deliver a winning combination of passive and active noise reduction for music lovers who are looking for a little peace and quiet on the go. Designed with soft, vinyl closed cushions that create a seal around the ear, the QZ Pro creates a passive, mechanical seal that reduces ambient noise while retaining bass frequencies.
Koss' active noise reduction circuitry is built directly into the ear cups using tiny microphones that sense surrounding low frequency. Information about the undesirable sound waves is processed through the circuitry and creates an "anti-wave." The sound wave and "anti-wave" counteract each other at the wearer's ear, reducing the irritating low frequency noise and increasing listening pleasure.
Designed to reduce low frequency, repetitive noise, the QZ Pro is most effective at blocking out noises you want to eliminate while not affecting things you want to hear, like voice and music. The QZ Pro affects those noises between 30Hz and 1400Hz, allowing music and voice to come through loud and clear.
It's no lightweight when it comes to sound reproduction. A deep bass and balanced midrange deliver an impressive sound performance whether you're enjoying a DVD, CD or MP3. An extra-soft, padded headband allows for lightweight comfort for extended listening periods. Completely collapsible, the QZ Pro makes an ideal travel companion on a plane, bus or automobile.
No need for noise cancellation? No problem; unlike some competitive models, you can enjoy the Sound of Koss with or without noise reduction. The QZ Pro noise reduction circuitry can be turned on and off with a flip of a switch.
