When I'm wearing my bluetooth earbud, I notice the guitar in the song I oftenly listen to that should be in the left side, heard from the right earbud. I realize that sound in the left earbuds moved to the right earbuds and vise versa.

I've tried every solution google give me but non of it not working (like factory reset and knock the earbuds for several time). How to actually fix this problem??
