Mismatch AirPod

Apple support has an article online (link below) that may help you:

What to do: If you see an alert that says "AirPods Mismatch" – Apple Support

Seems there is no way to identify the owner.

Only a way to track your own missing airpod ... if "Find My" is turned on.

(which may also find the owner of the lost AirPod.)
