Airpods 3rd gen replacement
My airpods 3rd gen is still under warranty and I have them replaced because it doesn’t connect for some reason. And the left one doesn’t work anymore. Now, I got my replacement and the serial numbers of each piece are different. And I only have 90days warranty on them at the mobile care shop where I have it replaced. Are these pieces second hand? I checked the serial number of both ear piece and it says invalid. Only the case is detectable for serial number check.
So I wanna know if they are secondhand.
