Unisar TV Listener TV920 TV Listening System
The TV Listener J3 TV920 TV listening system works just like your TV remote control, sending an invisible infrared signal from your television or any other audio device to the lightweight headset receiver. Unlike radio frequency devices, infrared technology is not subject to interference from microwaves, wireless networks or cordless phones, tuning adjustment or frequency drift, and the battery life is longer. The headset receiver then converts the light waves back into high fidelity stereo sound. The headset recharges when plugged into the transmitter and works for over 15 hours of uninterrupted use.
