Ever since I wrapped my earphones up and put them in my pocket, I've been getting these weird sticky sounds coming from my right earphone's housing whenever I move its wire which didn't happen before (but not the left, which seems perfectly fine). It also faintly feels like something's moving around in there if I hold it by the casing, too. It's not really a big deal (and barely noticeable), and doesn't seem to be affecting their performance or anything, but I'm not quite sure what caused it, if there's a way to fix it, and if it might be a bad sign for the long run. I was wondering if someone could help me figure out what's going on. Thank you!
