The FastStream codec allows both music and call channels to work simultaneously.
The Leaf supports FastStream and if used together with a FastStream compatible headphone will deliver much better stereo sound while in CALL mode.
Currently there are only a few headphones on the market that support FastStream (though this number is increasing). If you want to use this feature:
- If your Bluetooth headphones support FastStream and aptX, you need to upgrade firmware of Avantree Leaf by yourself (DFU) to set FastStream codec to the highest priority.
- Find a pair of Bluetooth headphones that support FastStream
- Purchase a pair of Avantree FastStream supported Bluetooth headphones, such as - the Avantree HS063, Avantree ANC032, Avantree ANC031, Avantree DG59 set, etc.
