Using Bluetooth headphones with a built in microphone doesn't seem to kick the microphone on. Unsure if it extends past specific brands or types but doesn't affect any other app on my specific device, I'm specifically using gen 2 airpods. Elaboration:
Connect headphones to phone
Launch VRC
Audio plays fine
Only internal phone mic used
Disconnecting them causes no issues, I get a notification and audio changes to phone just fine. Reconnecting them also works in changing the audio to the headphones. But the mic is never activated. Attempted launching VRC before and after connecting headphones with no change. Mic input option doesn't seem to exist and defaults to Android default input with no selection option.
Unsure if BT mics are even supported.
