Powerbeats fit- Right earbud stopped working for seemingly no reason?

Hi all, just dropping in to see if anyone has a similar experience or can offer some advice/troubleshooting.

I got a pair of powerbeats fit about 6 month ago. Been using them regularly, I like them and they never give me an issue. I use them at work and to exercise. I've never had an issue with moisture/sweat impacting the earbuds.

Yesterday I put them in, left works fine, nothing from the right. Is it possible the earbud is not charging for some reason? Has anyone had an issue with just one earbud?

I dont know maybe they did actually get too damp and there is an electrical issue. Are my earbuds done? Can they be saved or should I just look for a new pair? Ideally I'd like to keep this pair going. My last pair of beats earphones lasted me several years.
