Left AirPod making high pitched noise when inserted in ear

When I remove my left AirPod Pro from the charging case and insert it into my ear it makes an extremely loud electric noise. This can be replicated by pressing on the ear tip with my finger.

This is a much louder noise then full volume, and borderline painful if I put it in my ear. The noise lasts about a second, after that the AirPod will function normally until I put it back in the case...

I tried resetting them by holding the button on the back of the case with no change.

I think it’s a hardware problem (They are about 3 weeks old) but if anyone has any ideas I’d be happy to give it a shot.
