Are my airpods fixable after this or will I just have to buy new ones?

Hi, so my problem is my airpod gen 2s are kinda being funky.

So for about a year or 2 now they will connect like normal not too many issues there* but the earbuds themselves will die off fast like it feels as if as soon as I put one in I'm already putting the other cuz it died.

I just assumed maybe the airpod case I had was the issue so I tried resetting them and completely abandoning the idea of having a case. Since it was more for looks rather protection, since I take care of my devices well other then one incident where my sibling dropped an airpod into the sink while I was doing dishes but it was brief contact with water.

With that being said I've had them for about 6 years give or take and I used them everyday with maybe about a year n a half to 2 years of not using them so they are in fairly good condition.

*But for some reason it seems to hate my laptop (Chromebook not sure what model) it will connect to it and then disconnects immediately its odd I'm not too sure why that is I've tried resetting the airpods then too as well as the bluetooth and I've even taken the device off my laptop to reconnect it but still to no avail

So in other words I would really like some help with this odd occurrence it tends to get frustrating like being in calls or listening to music while doing things and then having to stop what I'm doing because they decide to act up so I'm looking for the most like inexpensive solution if possible since I can't afford any replacements. please and thank you!
