Finally pretty disappointed

I do not agree with the other reviews because after less than two years of use, my balance is not very positive.
First of aesthetically: once made the head is not very happy, very distant arches give the skull a curious oval to ALL OPERATING. Also following features enabled, the LEDs are lit and flashing which is not very discreet and can hinder lentourage.
The sound is also not unusual for a helmet that is not really cheap. Léquilibre particularly sound is very different with the active noise reducer. Sound filing then seems closer but much more compact and ultimately without much relief. The sound of my modest CX 500 ear-canal, necessarily limited on low, appears in more detailed comparison and enjoyable long term with sound insulation at least as good.
But especially the helmet broke down less than a year after the purchase, when I fairly lutilisais. The battery was hanging a few minutes after full charge and sometimes noise could be heard on headphones. After repair it worked well again a few months and then the sound rendering bluetooth sest degraded and headphones eventually stop working completely.
Given the reputation of the brand and the price level I mattendais to significantly better in terms of quality and reliability.
