Very interesting! 90

The sound is decent, maintaining the helmet is perfect and design is pretty cute ...
His black spot still remains that we can not adjust the size of the helmet! Indeed, the hoop is fixed and not adjustable so it ... sometimes interfere when wearing a coat or jacket because collar abuts against the headphone headband.
I also found that the kneecaps headphones were really small and so fragile! So I doubt if we accidentally sits on the headphones, the headphones are attached to the helmet ...
To see!
Without that, it is a helmet that I recommend to anyone looking for one that remains fixed to the ears despite our movements without it bulky nor too light.
