The case of my airpod pros is lost... in the event that I bought an a third party one from amazon will it work with the airpods and pair to other apple gadgets?
First, you should try to locate the case using FindMy. Have you tried that?
I would be cautious in purchasing a third party replacement case since the functionality of the case in not only charging the AirPods, but also in resetting them and synching the AirPods, is important in maintaining all of the functions of the AirPods themselves.
It looks like Amazon has a few different replacements that they are offering, typically selling for $35 or so. Reviews are mixed, some claiming the cases work fine, others just the opposite.
Alternatively, you can purchase a replacement case from Apple, and you won't need to worry about those things. And if there are problems, then Apple will support resolving them.
It will be more expensive, but that would be my recommendation.
Third-party cases are not likely to work the same. They miss the H1 chip, are not updateable with Apple Firmware, will likely interfere with AirPod firmware updates, and likely do not match the carefully engineered charging profiles.
