First observation: the helmet is really nice and pleasant to the touch. The pads are probably the best that my ears never passes known, and plastic is quality.
Regarding the sound, I have immediately felt the difference. People say that the sound is "broader", but the first words that came to me at first listen was "deeper". Indeed, one has the impression of senfoncer in music and to be able to hear inaudible subtle details with another helmet. It's a really beautiful feeling is very surprising the first time!
JOperation helmet several hours every day for several weeks now, and jen'm still satisfied. Several points regarding sound are appreciable, notament that the bass is very well balanced and have good presence without any sound into puree (David Guetta abstain fanboy), and the same is valid for the treble. Something very significant: try Decouter tracks whose volume is the rhythmic high and fast and have a break where the sound of a sudden stops. The effect dabsorption and absolute silence is really impressive!
In short, it comes very best headphones that I bought for myself!
