Koss 165789 Noise Reduction Headphones With Leatherette Over-the-ear Folding Design

This item is brand-new, factory sealed.

The Koss Quiet Zone QZ PRO headphone delivers 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 QZ PRO creates a passive, mechanical seal that reduces ambient noise while retaining bass frequencies. 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.
