The headphone case(AirPods 4 with ANC) makes a strange noise
My headphone case makes a strange sound when I pick them up or put the earphone on charge, it always happens differently and lasts about 5 seconds. What could it be? I'm already tired of this sound (it's not the charging sound or another sound since I also have AirPods 2 pro and it doesn't have such an annoying long sound
