BeHear Link+ is a long range, low latency, optical and analog wireless TV audio and music transmitter. It connects to the digital optical interface or analog sound output on any standard television or other audio device and transmits the sound directly to your BeHear headset. Alango Technologies’ sound enhancement technology clarifies speech and the Bluetooth connection eliminates ambient sound interference to provide you with the optimum listening experience. The BeHear Link+ audio transmitter is designed to help viewers comprehend television dialogue and enjoy programs without increasing the volume beyond levels comfortable to other viewers. It also enhances the listening experience for other audio sources. The BeHear headset can be connected to the BeHear Link+ TV transmitter and to a smartphone at the same time. This allows you to watch TV with the ListenThrough technology activated (passing through important ambient sounds via the headset), while also allowing you to make/receive phone calls.
