The IS410 from Sennheiser is a high-quality assistive listening system that allows a user to adjust the volume of a television, radio, or home stereo system to an appropriate level. The cordless, infra-red system offers excellent sound quality and range between the transmitter and the stethoset headphones. The headphones turn on automatically when a user puts them on, and the volume and balance controls are built in.
Simply connect the transmitter unit to your TV or other audio device, and it will wirelessly send the audio signal up to 12 meters to the headphones. A compression function on the transmitter provides excellent speech intelligibility and music reproduction. The headphones run on a rechargeable lithium-ion battery for up to 16 hours of enjoyment.
