It is a good helmet ... but. Advantage: Automatic release when it is placed on the head (detection by trying the internal arch) Recharging base very convenient, stable, easy installation. Good (even great) sound quality (no complaints from my point of view). No "breath". It does not hurt the ears (at least to mine) and is not too tight head. Disadvantages: This headset does not isolate you from outside noise at all! It is therefore to be regarded as an "open" headphones. His light on the head is correct if we do not move too; but if you are lying (in bed), or that stirs a bit too: there he moves and slips a little. It uses specific batteries, irreplaceable by standard batteries when they are dead. Only disposable batteries AAA (R3) can be used instead (accuracy of the record).
