| Marketing Information: | The Koss QZ5 stereophone is an extra-durable stereophone that delivers amazing passive noise reduction. The QZ5 was initially designed for use with racing radio scanners and metal detectors users, and provides a behind-the-head headband design. Since then, the QZ5 has become a favorite for a wide range of listeners who need to cut high levels of ambient noise and do not want the constraints of a conventional headband. Built to withstand the rigors of outdoor or indoor use, the QZ5 features both a 3.5 mm and 6.4 mm plug and will connect to most radios and scanners. |
