I've also got an Avantree DG80 as a workaround and I can confirm it works with my Trekz OpenComm headset. It supports sounds up to 8 kHz (corresponding to mSBC with a 16 kHz sampling frequency) with the mic enabled, while anything connected directly to Linux bluetooth only goes up to 4 kHz in HSP/HFP mode (CVSD). The sound with mSBC is still noticeably worse than in A2DP mode when listening to music, but a lot better than CVSD.
