What do I do if i tried resetting my airpod case and ome of my airpods is saying its charged but wont turn on. And its been like this for a year and nothing is helping.

I’ve had these hand me down AirPods for like a year, and the original owner took really good care of them, and so did I but one of them, despite my persistence, shows up charged in the case and on screen. (It’s says 100% and the case is green when it’s in their by itself) but when I try to use it, it doesn’t connect or make noise at all. I tried resetting the case and cleaning it and nothing is working and I don’t have the money for a new pair.
