Goooood

I already had the Bluedio q2 headphones for sports and I was fully satisfied with the blow I fell for this helmet promo, 29 instead of 79 for a quieter operation.
I'm not a melomane but a normal user, my first impression is that this is the helmet that of Beats although it might be me I feel that there is a very light whistle (echo suppression?)
The connection with my Nexus 5 instant and jack bonus is helpful.
Not tested in duration, jediterais this review to check the remaining, the manufacturer announced 45h! (Marseille .....)
If not in this price range I doubt the found better.
