I'm not disappointed with this headset that offers good sound quality and good bass. Nevertheless it requires music with a good base of his otherwise it accentuates the defects. It is true that we pay some brand and design (in my opinion very successful), I would not have taken if I had to pay the full price .. It is comfortable on the ears but not for those who like to keep a helmet around the neck all day, and it is relatively heavy but solid enough (helmet as double jack). Otherwise in general, I think it's good to see very good stuff great lover of music demanding.
