Comfort is excellent, hardly supports helmet on the head. It is light and simi-li leather is of good quality even if he messed it quickly but nothing too bad.
The helmet and really well made and there is an included carrying pouch, the quality of plastics is excellent. We really feel like a premium product in hands.
Insulation is good and in the street no one will hear your music, and you will not be bothered by the small noises that handed environant significant noises (horns ect ...) will be reduced and muted. Inside the night in total calm, the headset leaves virtually no noise escaped but slightly understood (together with insulation 100% is practically impossible)
The audio quality is very good. The entire spectrum is detailed and well balanced. The low end is more powerful than my HD 555, the bass is detailed without becoming effect "boom-boom". The midrange and treble are good also. The headset has a good spatialization for a closed helmet even if the sound is a little compressed and not staining and mounted power of HD 555, but hey it's a closed helmet! The sound is quite dynamic and rap / rnb and other music like rock ect ... these headphones give the best of himself! In the other style it will give a good sound image but on this one I'd rather not say anything because I was used to my HD 555 that better on instrumental music manga, films (for me) because the acute and sound in general go up higher.
This is a great product that deserves quite 5 stars.
