I just bought a pair of Urbanears Kransen earbuds, but they're partially not working on my Galaxy s2. Whenever I plug in the earbuds in certain parts, the sound becomes very distant and tinny, and most of the time the main vocals don't play at all, but if I move them to another position, they play perfectly. I switched from a pair of V-Modas but never experienced this problem with them before. Another thing to add is that I've also tried the Urbanears on an iPhone, and they've worked perfectly. Does it have something to do with the phone or is there a problem with the earbuds themselves? Please help!
