I have the same issue with my EarPods… I tried removing the earwax from the sound holes following steps I watched on YouTube nd somehow water got inside, the problem (distorted sound)I was trying to fix got worse so I went ahead to open it. When I opened it I couldn’t understand it’s workings so I just closed it back and luckily for me the sound was restored but after a while it got bad again. The problem is from the speaker it self after opening it it’s almost impossible for your EarPods to be the same. I’m crying.
