hey Eric, happens on both my MacBook Pro and IPad Pro.
Both on YouTube and Apple Music - (as I said before) as soon as I take them off my ears the sound still plays in the left channel for 5 seconds and then noise cuts out completely. Bluetooth connection drops and reconnects to whichever device (and the connect sound plays)
As I was typing this up I still had them on my head (with no sound playing) the left channel clicked once and disconnected again. I’ve also tried disabling the head detection but it made no difference.
I left them charging overnight, not getting a charge light when plugged in (but the AirPods are coming up with 100% charged)
Please note too, I’m in New Zealand and there’s no official Apple store in the country.
Sorry, I have also followed those reset instructions too, no difference
