It has happened to me three times. When it happened the first time, I called Apple and they replaced my ipods because I had only had them 11 months (I didn't have applecare, but they said less than a year was replaceable at no cost). They only replaced the pods themselves, not the case/charger. The new pair started doing it within about 3 months, and Apple agreed to replace it (and I think I remember them saying something about a limited 90 days for replacements), but the tech told me on the phone "this is the last chance," which I thought was kind of reversing the roles a little, but ok. My new pair, which I have had a month, just started cutting out again. I have switched to the left side, and will see if that is a long term fix. But this is either (a) a problem with my case which has never been replaced, or more likely (b) a universal defect. It's pretty frustrating, because i use them all the time for phone calls, zoom calls, etc.
