Koss JR900 RF Wireless Headphone System

The JR900 from Koss is a high-quality wireless stereo headphone system that allows you to listen to your favorite audio sources without the hassle of wires. The system consists of an RF transmitter/charger and a pair of stereo headphones. The transmitter has RCA and 3.5mm connections, allowing you to hook it up to your TV, DVD player, computer, home stereo, MP3 player, and more. It offers 5 selectable transmission channels, allowing you to find the best channel for clear transmission. This is also useful for multi-system use in professional venues, such as theaters, museums, and more. The transmitter provides a wireless coverage area of 70,000 ft², providing listeners with a high degree of freedom.

The headphones have thick around-ear leatherette cushions and an adjustable vinyl-covered headband to provide long-lasting comfort and noise isolation. Large NdFeB magnet drivers, Mylar diaphragms, and OFC voice coils provide crisp, detailed audio with a wide frequency response. A built-in dual volume control allows you to make level and balance adjustments without having to return to your audio source. The headphones operate for 5-10 hours on the integral NiCad rechargeable batteries. To recharge, simply place the headphones on the transmitter.
