Koss QZ-PRO Active Noise Canceling Headphones

The Koss QZ-PRO headphones deliver a winning combination of passive and active noise reduction (ANR) 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 Koss QZ-PRO creates a passive, mechanical seal that reduces ambient noise while retaining bass frequencies. Designed to reduce low frequency, repetitive noise, the Koss 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.
