the headphone stop work after my 3rd or 4th run . I shorten the wire and use only the top half . I find that I really like the short cord and do not worry about the broken bottom half of the cord . I suffer a personal set back and be not able to exercise or use the headphone for several month . I recently start use the headphone again and after another 4 run , they be indeed break . I try they on other music player and still get nothing . I contact the seller and they say I be out of the 3 month warrenty . I be hope they could\/would be willing to fix or exchange my headphone . -lrb- not really one to spend this much money on headphone -rrb- . they do not even entertain any notion of compensation . how come the consumer can not have a policy ? my policy be a set of headphone should last longer than 10 use or 6 month . I live in a dream world I guess .
