Helmet relatively convenient. Quickly paired, controls easy to find by touch, sound very good with well restored serious, no crackling. For music, it is quite ok. Listed phone, it requires speak loudly to be heard and if the person on the other end put on speaker phone, she grabs any interference. I do not find it convenient to set up because it wraps all the time about himself, I guess it's a matter of habit too. By cons, once set, it does not move, stays in place and soft cushions makes it enjoyable. It does not obscure outside sounds like headphones-ear, but his power developed perfectly covers. The controls (volume levels, change titles and Pickup) are on a single headset but so well separated for each function, and symbols are embossed. It is therefore easy to control blind. Lightweight and wound on itself, this headset takes up little space and easily fits in a pocket or purse. It charges via USB on PCs, external battery or wall charger without problems and the cable is provided.
