I have a crackling sound in the left AirPod

See this thread: https://discussions.apple.com/thread/253298219

It seems to be an extremely common issue. Hopefully apple will get that fixed soon, or I'll be returning mine. Other than the ringing/crackling, they have great audio quality. The thread I linked has instruction on how to temporarily fix the issue through accessibility settings. Try that out and see if it helps

Good luck.

No problem. I haven’t tried to return yet, I am hopeful a software update will help, but I’ll definitely return if we get to the 1 year manufacturer warranty and nothing has been fixed. Good luck! :)
