What is the case firmware on first generation AirPods pro

Stidge is asking about the "case", NOT the AirPods themselves. Cases have a different firmware version (e.g. my AirPods Pro 1st Generation Case's firmware is currently listed as 1.3.9). I, too, have not be able to find where Apple officially lists the version history for the AirPod Pro CASES.

Hey stidge,

Apple actually just released a firmware update yesterday and it is 5E135. That is ranging from the 2nd Generation AirPods all the way up to the New AirPods Pro 2. So your AirPods Pro 1st Generation should be on no later then 5E133. (Which was the previous version).

Hope this helps! :D
