I bought this helmet at Amazon.com and I received it fast enough so I'm happy with the service.
If to talk about these headphones. This is a very good helmet, beautiful and strong. The sound is excellent but if you are looking for a lot of bass or if you listen to a lot of song kind of rap, hiphop rnb and then go your way because the bass is not as present as another helmet.
So overall, I'm still happy despite the lack of bass, otherwise wearing this helmet can hurt a little at the top of the skull (well it depends on the morphology of each).
Finally I recommend this helmet for those who rather likes electronic music. Last thing, the cable is a bit too long if you want to take it everywhere with you.
I hope this review may help you in your choice.
