Hi! I've bought one of these Invisible Spy Earpiece inductive Earphone Wireless Gsm! - eBay (item 180355165720 end time Jun-07-09 19:40:30 PDT) from ebay. But I can't hear with it well. The volume of the sound is very low, even when I increase up to max the volume of my mp3 player(phone) and put the earpiece deep in my ear. And I'm not deaf. Can someone tell me how to fix it, please!
