This helmet keeps its promises: the sound is worthy of competing headsets 100 (see best) for a much lower price. The finish is quite good (it's still plastic, but for that price you can not find the metal anyway), and the ability to fold the headphones under the hoop for the trip is very welcome (compared to my old helmet with fixed arch, it takes half the space in the computer bag, happiness!)
terms of comfort, it is always a matter of taste, but I found nothing wrong with it, much lighter than my old helmet and mosses are very comfortable. Furthermore, its excellent insulation makes it even better.
