So i was normally using my moondrop chu2, and then i suddenly noticed one of my earbuds sounded very low on volume, i tried plugging them into my phone laptop, but its the same, so i opened the whole thing, i saw blue-greenish substance, i think its some corossion or something, and then when i unscrewed the metal piece on each earbud, i saw a mesh inside, and one of them seemed wet or something, and when i removed the metal piece, both sounded the same, so i think its the metal piece or the mesh inside which is bad? what did i do wrong, what should i do now?
