So, as the title suggests, I own a pair of soundcore space a40s, and they lost a bit of their functionality a while ago and I hadn't been using them but I recently picked them back up and was wondering how fixable the issue is. The left ear is significantly quieter than the right. Like, if you have both in, you won't be able to tell the left is working until you take the right out and realize it's making very faint noise.
My main question was: is this something I can fix at home?
I'm willing to take them apart (if that's an option) and try to fix them myself, and if the issue likely stems from something pretty easy to fix, then I'd be happy to.
If not, are they fixable at all? As in if I took them to a professional?
