Chirping noise in left AirPod 2 Pro during transparency mode

It chirps only in left ear, at about every 30-45 seconds. Happens when listening to Bluetooth or just hearing tv or conversation. If you turn off ‘noise control’ or anything ‘except transparency’, it eliminates the chirping. Put it on transparency, it chirps. Solution: don’t use transparency! 👨🏼‍💻
