Can we do better or do better on time today? I personally do not think so ... This headset brings comfort, lightness and satisfaction. Already we can say is that autonomy is very long. For example, if you forget to turn it off, this one goes alone on standby. So you can enjoy them for quite a few days without recharging (and that's really super cool)! What there is appreciable, too, is that we distinguish perfectly sound. If it is set up course. For example drive, communication is very good, because the sound is smooth and relatively accurate. When there is wind outside, no problem for the person with whom you correspond, the person on the other side of the phone will hear no breath in his handset. Then when you turn it on, a voice tells you the remaining range, it's very convenient not to fall in the harbor by surprise. I give 5 stars without hesitation for this marvel of technology. The only gripe we can do it, is that the voice is in English and not in French. Too bad for that little detail.
