Let me explain, I bought the helmet 23 March 2014, it had a micro problem in early May, which forced me to let me replace (received May 8, 2014 is approximately 1 month).
But now I find myself again with a micro problem, headphone, plus the upper bearing of the skull that it takes off (only 2 months).
In addition I would add that the headset abominably head shakes loose even thoroughly.
The sound is good, except the bass are very poor despite good setting.
Adding a gadget (removable right earphone) to "DJ" totally unnecessary and disturbing because it never stays in place, so imagine a helmet that greenhouse, whose micro kidding, with poor low quality and unnecessary gadgets and disturbing.
Here I think to avoid unpleasant surprises people who will read this comment.
