it's been about 6 months since I use these headphones (often several hours per day) and I totally conquered ... the sound is soft, good bass, super insulation, and treble are not garish contrast to intra headphones Apple ear (the high end from Apple). the only downside is that I find that the foam end caps are not very hygienic and I do not know how long they will hold (but hey, it's been 6 months and everything is fine). I advise those who seek headphones to the subway or the bus without enconbrement a big helmet.
