What is A2DP?

What if my Bluetooth phone does not have A2DP?

You will still be able to use the Bluetooth handsfree functions of the X5 and Sonic with your mobile phone while streaming music from a PC. When a call comes in, the music will stop and you can answer the call. To enable your computer to have A2DP, use the external Bluetooth USB Dongle that comes with the Sonic …or the audio streamer that comes with the X5. Though many devices already come with A2DP, for the X5 you can A2DP enable any audio device (TV, DVD, PC or Mac, Stereo, MP3 player, iPod etc) using our included “A2DP streamer”.
See below for a full list of the latest devices supporting A2DP.
