One of the best helmet in its class. (Ranked # 1 in its category in a famous IT site) Flawless sound reproduction and pure, deliberately loaded in low but not intrusive or artificial feel, the sound is super nice (and therefore reserved for listening rather rock or metal). You can remove an internal filter to find a more balanced sound but must be removed the headphones (far from practice). Its vintage look is particularly successful and participates in its rock'n'roll image. It is well finished and looks very solid (metal arches not to break), plus it folds up for transport (small pouch included). Negative point, he shakes his head a little and can be uncomfortable for some over time, for my part, despite this a bit surprising at first, I actually found it very comfortable and well insulated (diffuse nevertheless a little too much its outside and can hinder the entourage). Short to recomend for the purists of rock and metal. Is its high price anyway.
Small update after several months of use: Always so good in sound but some delicate components. The spring at the jack is gone and one of the bases of a foam earpiece tends to go alone (only magnetically fixed). A so handle with care.
