Sound Quality Issue / Rattling after APP Gen1 Dropped in Driveway.

My wife dropped her AirPod Pro Gen 1's in our driveway before leaving for work. She realized she only had one earbud when she got there. When she got home she found the other one in the driveway and we're pretty sure it rained on it while she was there.

Both earbuds still connect, charge, and switch into/out of noise cancelling, but there is a noticeable rattle with the earbuds and especially when they are touched or jostled. The rattle sound is more in the left ear, but there seems to be a slight rattle in the right ear as well. Figure they are probably toast, but wanted to see if there is a way to repair them or replace them cheaper than Apple would at $89/ea.
