Until we can finally kill HSP/HFP, I'm never gonna be happy with Bluetooth. Using a headset mic shouldn't blast you back to the telephone era.
What’s hsp/hfp?
It's the Handset Protocol/Handsfree Protocol that was developed for simultaneous sending and receiving of voice data. They're the only protocols that support sending and receiving voice at the same time, and they do that by sending mono telephone quality audio and receiving mono telephone quality audio.
It's why most gaming headsets, even ones with Bluetooth, include a small RF dongle separately. Bluetooth is technically incapable of high-quality audio when recording.
