Under Dual Link Mode (connecting with 2 headphones/receivers simultaneously),
the transmission codec will be the one with longer latency, eg: If one device
supports aptX LL and the other only supports aptX, then the final transmission
codec will be aptX; If both headphones supports aptX LL, the final transmission
codec will be aptX LL.
