On paper, this headset is perfect, the two stereo channels in the same headset, an air tube for not radiation directly into the ear, and a rather nice design a fair price. When it was in the hands, it keeps the same good impression, the product of air quality, it is pleasant to the touch and to the eye, several tips, very comfortable to wear ... then one launches music and there is the drama. The sound quality is really, really sad. I suspected that with the air tube, the quality is not as good as a conventional headset, but I never imagined it was so. The sound really "crushed", you lose all the details, it seems to have the mids and many, many serious. In short, 2 star anyway for quality and comfort, but if we had to judge only on sound quality, the note would be negative.
