These are the wireless TV headphones that receive a clear audio signal from 100' away, even through walls and ceilings. The included 2.4 GHz digital transmitter plugs into a television with the included cables (3.5mm, RCA, RCA Coaxial, and Optical) and transmits audio to the headphones without using Bluetooth, Wi-Fi, or smartphone apps. They also have advanced technology that isolates voice frequencies, lifting dialogue audio without increasing a movie or program’s background noise or music. The headphones’ earcups and top are padded for plush comfort and powered by two AAA batteries (included) that recharge via the transmitter; a full charge provides up to 10 hours of power. Transmitter plugs into AC with included adapter. 10" H x 9" W x 3 1/2" D. (1 lb.)
