Race Tracker Passive Noise Reduction, 40-20000 Hz, 3.5/6.3mm, Black
The Koss Race Tracker stereophone is an extra-durable stereophone that delivers amazing passive noise reduction.
Like the QZ99, the Race Tracker was initially designed for use with racing radio scanners and metal detectors users, and provided a behind-the-head headband design. Since then, the Race Tracker 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 Race Tracker features both a 3.5 mm and 6.4 mm plug and will connect to most radios and scanners.
The Race Tracker features neodymium magnet structures for outstanding clarity and definition.
Closed, Pneumalite™ ear cushions and extra-secure headband pressure create a complete seal around the 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 your user flexibility.
The Race Tracker features an 8-foot, coiled, single entry cord.
Built to last, the Race Tracker is covered under Koss’ Limited Lifetime Warranty - the only warranty of its kind in the stereophone industry.
