I must say that the sound quality of this phone be really good . however , when it come down to comfort this headphone be anything but comfortable . if you be a runner that like to run for 1-2 hour and listen to music then I do not recommend this headphone . not sure if the people who give this a 5-star rating have ever use this headphone , because once you use it for more than 30 minute you ear will start burn . the headphone be strong , but that make it rough on the ear . I be actually search for a better heaphone -lrb- perhaps a sennheiser that will satisfy all need -rrb- as I be write this review .
