a very high fidelity headphones that really has nothing to envy to many fashionable helmets "dr DRE" very good sound, a sensational comfort, robust design with materials such as aluminum and leather. it encompasses both the ear without being too big, very light one does not feel it on the head and finally the fact that this is a helmet "open" is not a problem despite the fact that I do not listen to music loud, I'm not embarrassed in the train or on the subway. want to please you feel free you rediscover your music.
