The JR170 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 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. The transmitter's internal microprocessor then automatically selects 1 of 2 channels for clear transmission at distances up to 150'.
The headphones have thick around-ear cushions to provide long-lasting comfort and noise isolation. Large NdFeB magnet drivers and OFC voice coils provide crisp, detailed audio with a wide frequency response. A built-in volume control allows you to make adjustments without having to return to your audio source. The headphones operate for up to 25 hours on a pair of AA batteries.
