Negotiated SBC XQ implementation
A2DP spec v1.2 states that requires all SNK implementation shall handle bitrates of up to 512 kbps (which correspond to bitpool = 76). According to http://soundexpert.org/articles/-/blogs/audio-quality-of-sbc-xq-bluetooth-audio-codec , Transparent CD quality can be reached in DUAL CHANNEL MODE, with bitpool ~ 38 per channel : SBC-XQ. This has been tested on numerous devices with no issue.
