I've got a set of Pixel Buds A Series that seem to have painfully weak magnets, causing the buds to constantly lose contact with the charging pins. And since they're always turned on when disconnected from the charger, this means my buds will randomly pair to my phone even though they're both in the case, muting my sounds and preventing me from hearing notifications when I'm not wearing the buds. It's super frustrating. I feel your pain.
