Hi @NRC, and thank you for your recent message!
The supported pairing profiles for the Soundbar 700 are A2DP and SBC. This runs on Bluetooth version 4.0.
The system will remember the eight most recently paired Bluetooth devices, and will attempt to reconnect to these in the order these were last connected.
I hope this helps, and please let me know if you have any other questions 😊!
