Everyone in the room can watch TV and listen with their own headphones when using the BTA1 TV Transmitter with Auracast from Sennheiser. The BTA1 connects to a TV or receiver via optical, HDMI (ARC), or 3.5mm connection. From there, it can pair to a set of Bluetooth headphones or use broadcast mode so everyone can hear. In broadcast mode Auracast technology transmits the TV's audio like a radio station, and any Auracast-compatible headphones within range can listen and enjoy individual control over volume and feature settings. This feature improves dialogue clarity, making TV shows and movies easier to understand without needing to raise the volume or use subtitles.
