The helmet itself is disappointing. On the plus side, the sound is good, in 7.1, as said, do not worry with the microphone at the beginning, I like the design (blue LEDs are cool in the dark, haha) ...
Where the rub is in terms of comfort, robustness and after-sales service. Being accustomed of extended wear, I was forced to withdraw because my ears were compressed and hurt me (they were red). So comfort level, not great.
Having a rather long face, I had to adjust the height of the helmet, normal. By putting the headphones quite normally, without forcing, the right branch of the helmet broke as it could break a twig.
After that, recording me for the warranty, I contacted customer service and found out that the reference to the United States was the customer's expense (costs which amount to roughly the price of the helmet, sent from the South of France).
So I end up after two weeks of use with a headset whose branch holds with tape (and frankly it's not terrible), with a helmet that hurts my ears (and REALLY bad) and whose micro sizzles (because the thread passes into the branch and obviously, having to forcibly remove and replace tape he finally sabîmer).
In conclusion, I do not recommend this helmet, because after two weeks, I have to buy another.
