>From what I can gather this is not a function of the headset or
Bluetooth device, but it's a function of firmware differences in the
host side Bluetooth adapters.
For example, I have a Sony WH-1000MX3.
I have a USB dongle adapter that does not work in the HSP/HFP mode. When
selecting the mode the active profile throws various errors then returns
to the "off" PulseAudio/ALSA profile.

I also have an Intel Bluetooth/WiFi 802.11ac card (Bluetooth is on the
USB bus), that does support the HSP/HFP mode, abet with noticeably
reduced audio quality. I think there is a separate bug in launchpad
tracking the audio quality issues of that mode though.
