The wireless headset comes with a Quick User's Guide, but perfectly clear. The language choice made, the Bluetooth pairing is no problem other than those related to the devices to which it connects. With a Windows phone - iPod, everything is easy, with a portable Sony Vaio, once entered in the settings read / write, everything is possible (music, video, Skype), with an Android tablet, it is a little more complicated, but mine is old. The headset stores the two last connected devices. It is very talkative, but his comments are disengaged rather useful. The battery seems to hold a charge, of course as usual, it is better to think about recharging. The sound is excellent provided you do not stray too far from the source. As for the Windows phone, in conversation, to consider the quality of the network. A wireless headset together with a carrying case and a cable for a conventional use. Everything is there.
