Small concentrate our innovative technology representative time, this headset is quite impressive: it easily pairs with iPhone, fires alone once positioned in the ear (by making you know) remains fairly stable despite its apparent volume (if you avoid the dangerous-jumps), meets the finger and the eye and loads easily into a small box that itself serves as load reserve (ie it can load the headset without connecting to the computer ... if having previously loaded). The explanations are succinct, but ultimately this high-tech toy is used quite intuitively. The downside? The consideration for this lack of power button (which the headset is instantly operational) that it will discharge very quickly, presumably alone when in the pocket ... which makes its use enough ultimately impractical. Too bad.
