Some months I use this headset daily. No complaints about the sound quality, comfort or design ... By cons, it is really too fragile ... After a month, the plastic strips (which are used to adapt the helmet to the head ) broke both. I have a small head, so I can put it without extending the branches, but it is a pity that the plastic is of such a poor quality.
4/5 for sound. 1/5 for the strength ...
Edition a week after the first comment: The helmet broke, net ... was taken: 4/5 for sound. 0/5 for strength
