Wow, this is wild to hear. That’s exactly what happened with my Gen1 AirPods. Loved and used them so much but a little after a year the right one died and they were like, “sorry your two-months past.” Purchased a second pair, Gen2, loved and used them so much especially for work now that all is by distance…would you believe the same thing happened again with the right side? I noticed it faintly getting progressively worse about a year out. I tried for weeks to contact the store where I purchased to no avail, just not answering and I live an hour’s drove from the city: not going to drive two hours and expose to crowds unnecessarily during the pandemic without even knowing if this could get solved. I eventually contacted Apple…after an hour on the phone with a lame tech who seemed to know less than me (am an everything Apple person for decades) I finally got a Supervisor, explained the situation that I started trying to address this right around the one-year mark but now it’s three months past. He took it all in and ordered a warranty exception to replace both buds but I had to return the originals. Guess I’m a believer and loyal Apple man again, but we can say the right earbud problem is replicated, and twice for me across two generations.
