Product Description

The QZ99 Passive Noise-Reducing Over-Ear Headphones from KOSS are designed to make the world disappear. Pneumalite(TM) ear cushions and an extra-secure headband help with passive sound isolation, allowing for listening without outside noise. A volume control is located on the ear cup for maximum ease of use.

Amazon.com

The Koss QZ99 headset is a passive noise-reduction stereophone system that isolates the listener from ambient sounds, allowing clear and focused listening of the intended aural signal. Ideal for use with racing scanners and metal detectors, it includes a volume control on the earcup for easy level adjustment, a stereo/mono switch for added flexibility, and a single entry, 8 foot coiled cord.
