Audio quality has always sucked on GoPros but the new Hero12 has Bluetooth connectivity for up to 4 microphones. Yes, I know it will pair with Airpods but I want to run a microphone at the back of the car for some cool exhaust audio and the Airpods won't work for that unless I jerry rig something. Has anyone tried an external Bluetooth microphone with a Hero12? What mic did you use? How good was it?
