AirPods Pro issues

Hi everyone,
So, last month, my AirPods pros unfortunately went through the washer. They still kinda work, but with some major issues. For example, I can hear people on phone calls, but they can't hear me. Transparency mode doesn't work at all. When I put the AirPods back in the case, audio does not transfer back to the phone like it should. I have to turn off Bluetooth in control center before removing them if I want the phone to start speaking again. And finally, the case shows the battery at 60% no matter what. It still takes a charge, but no way to know where the battery is really at. Also, the right AirPod seems to be in worse shape, as the bottom magnetic piece started separating from the rest of the body. I pushed it back in place, but have been having the problems described above. They still technically work, at least as plain old headphones with no mics or other features, but this month I decided it was time to do something. So, I ordered both a used case and replacement airpod on eBay. Turns out that the first replacement pod got lost in the mail, and didn't arrive until today, but several days ago, I contacted the seller and let him know that it had not arrived, and he sent another right side airpod as well as a left side which I went ahead and ordered. Those two come in tomorrow, but I at least had hopes of syncing the new right AirPods with the existing left one which was in decent shape. I tried syncing with my old case and with the new one, and in both cases, I was unsuccessful. Not sure if the old case is just too damaged, or if the new one is also a dud or a fake. On Ebay just about anything can happen. Also, even though I can't get the new right side airpod to sync with a case or pair, it apparently did have enough battery to still activate anc or transparency. The clicky sound on each is different, which makes me wonder also if I have been using really good fakes all along, or if that is somewhat normal. What I can say is that with the new one, transparency sounded way better and more natural than it ever did with my old ones. It will be interesting tomorrow when the other airpod replacements come in, whether or not I can get these to sync with either case. I really need at least one working pair, as I hate using speaker on phone calls, but can barely hear the person on the other end.
So, having said all this, first off, please be careful and don't let your AirPods go through the washer! Also, have any of you ever had to replace an airpod, case, etc? How hard was it for you to sync them up again? Also, have any of you ever run in to fake AirPods Pro? Any idea on how to spot the fake vs the real thing? This has been a real mess. If none of the replacement pods sync with the replacement case, I would imagine that something is definitely up with the case. Any tips or tricks for getting these to sync up would be much appreciated.
