I buy the in-ear headphone look at the review post here and be I glad that I do . . the in-ear headphone be really good . I doubt if I can buy anything like it compare to the price I pay for it . one reason for I to buy it be because it have a support that make the in-ear headphone cling on to the ear and not fall of while run . try use traditional headphone earlier and it will just not stick on my ear . just after run couple of step the traditional headphone would fall off but these wont . . so happy with the buy . . BTW the sound output be really good for a good hour of music . . the more you burn -lrb- use -rrb- the headphone the better sound it give . I will not be hold responsible if someone will literally burn the headphone . ; -rrb-
