Koss QZ-99 Passive Noise Reduction Stereophone

The Koss QZ-99 is an extra-durable stereophone that delivers amazing passive noise reduction. Designed initially for use with racing radio scanners and metal detectors, the QZ-99 has been a favorite for a wide range of listeners who need to cut high levels of ambient noise.

Built to withstand the rigors of outdoor or indoor use, it includes both a 3.5mm and 6.4mm plug, and will connect to most radios and scanners.

Closed Pneumalite ear cushions, with extra-secure headband pressure, will create a complete seal around your ear, eliminating all ambient noise from getting through.

A volume control on the ear cup allows for easy level adjustment if the sound source is out of reach.
A Stereo/Mono switch extends user flexibility.
