A helmet that is stylish, beautiful finishes and a good sound. Attention, it is neutral, low are a tad too discreet, but with a few dozen hours of running, it will be great. Helmet that insulates the external noise, a little heavy for long use but nothing insurmountable. The sound is really good, of course, it will be used more on the good stuff and it will give satisfaction. There is no cap to Jack. Provide high-end extension to not spoil the quality of his helmet. But ... there are small flaws course: non-detachable cable, headset ... big big head. It can quickly find beuacoup too low. Important: function call / micro-compatible iPhone 5s. In short, for the same price there of all as good, but he is very good. A good pink Floyd running on the Rega and c is madness.
