Description
The AV:Link BTTR2 is a small 2-in-1 Bluetooth adaptor that adds wireless audio to almost any device with a 3.5mm or RCA connection. In transmitter mode it sends audio from a source such as a TV or projector out to Bluetooth headphones, speakers or a soundbar. In receiver mode it works the other way round, letting you pair a phone, tablet or MP3 player and play through wired headphones, an amplifier or a car audio system. One switch changes between the two, so you can move it around the house or take it with you when you travel.
Multipoint support means the BTTR2 can connect to two devices at once, which is handy if two people want to listen to the same TV through their own headphones. The wireless range is up to 10m in clear line of sight, and the built-in rechargeable battery gives up to 8 hours of playback when transmitting and up to 6 hours when receiving. A full charge takes around 2 hours. The compact 42 x 42 x 10mm body weighs just 20g, so it sits neatly behind a TV or clips easily into a bag.
Setup is straightforward. Connect the BTTR2 using the supplied audio cable, choose transmit or receive, then pair with your Bluetooth device. It runs Bluetooth v4.2 with aptX, A2DP and AVRCP profiles for stable connection and good audio quality across a wide range of gear. Whether you want to watch late-night TV without disturbing anyone or stream your phone through an older hi-fi, this little adaptor covers both jobs from one unit.
