Unisar TV Listener J3 TV920 TV Listening System

With the TV Listener® J3 TV920, one person can enjoy the television while the other sleeps, reads or studies. No more waking up your family because the TV is too loud. Also perfect for individuals with hearing loss, this completely cordless infrared system is ideal if you have difficulty hearing or you simply want to watch TV, listen to the stereo or any other audio device at a different volume than others. The disk transmitter and ergonomic headset deliver superior sound when used with nearly any TV or audio source, allowing you to enjoy your favorite TV shows or radio programs without wearing a bulky headset.

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.

What is an IR (infrared) system?

IR, or infrared systems, transmit sound via invisible light waves within direct line of sight. There is added security in an IR system because sound cannot "spill over" to other rooms. Many multiplex theaters use IR systems for that reason.
