Apparently there's a problem with these earphones. Some sort of product failure. I suggest do not try to open it up and fix it, it is likely be more complicated to put back. If u can bring it back to the store for replacement. I had mine replaced only to receive new malfunctioning ones, with the same problems. Now I am waiting for them to bring in new earphones from a different branch. All in all, it's been 3 months of on and off tango with the vendor in order to get new ear phones that are in working order. My advice to y'all, do not buy them, and if u did, try not to fix them yourself.
