headphones malfunction with iOS 16.5 both on iPhone 12 mini and iPad air 3

Check the charge status on your iPhone or iPad to make sure that each AirPod is charging . Put both AirPods in your ears. Play audio to test both AirPods. If an AirPod still isn't working, reset your AirPods or contact Apple Support.

If your left or right AirPod isn't working - Apple Support (IN)

I have issues too with my wireless skull candy ear pods. Only sounds that come through them now are muffled base noises.
