Bone-conduction headset

[Peter Flynn]

Does anyone have a recommendation for a lightweight Bluetooth 
bone-conduction headset with boom microphone that actually works under 
Linux?

Every single regular headset I have tried either

  * fails to connect to Bluetooth OR
  * connects but then dies OR
  * the headphone connects but the microphone doesn't OR
  * connects but fails to pass the connection to ALSA so it never appears

(currently on Mint 20.1 with whatever Bluetooth comes as standard).

I know Bluetooth is flaky as hell, and that Linux implementations needs 
extensive tweaking and testing with various combinations of packages to 
get to work, but surely by 2022 we should have a system that just works?

Or a recommendation for one of the Ubuntu-based distros with a 
fully-working Bluetooth system?
