Try and restart or reset them to see if the issues persist

Restart AirPods

If your AirPods aren’t working right, try restarting them. 

Do one of the following:

• AirPods (all generations) or AirPods Pro (all generations): Put the AirPods in their case, then close the lid for a minimum of 10 seconds.

Return AirPods to factory settings

If your AirPods aren’t working correctly after you restart them, you can return them to their factory settings. 

Do one of the following:

• AirPods (all generations) or AirPods Pro (all generations): Put the AirPods in their case, close the lid, then wait 30 seconds. Open the lid, then press and hold the setup button on the back of the case for about 15 seconds, until the status light flashes amber, then white.

Hope this works for you!
