I purchased these iems a few days back. Audio quality was very bad(ear piercing), so i kept them in drawers. Today I tried them once more and accidentally put my finger on the hole at the back of it. Sound improved a lot(sorry I can't describe in technical terms). Now I wonder why those are there at the first place and what should I do to permanently seal them?
