Can be switched off again via the function button, which you press a few seconds. When switching the phone recognizes immediately and without further action by the wireless helpers.
With the mini-headset can also listen to music, a call comes in, the stream is interrupted and resumed automatically after the call. An incoming call is announced in the earphones of an English computer voice with the respective number including country code. A look at the phone's display is there, however informative, because there the call is assigned a name, as long as the person is listed in the address book entspechende.
The headset supports Siri (the iPhone). Thus, for example, calls from the address book active, without having to dial. The package includes a total of three plastic earplugs. What the exact advantages and disadvantages are, I have yet to figure out, but a selected, with whom I while driving - can cope well - and since I use the device.
For hands-free telephoning the wireless helper is thus well suited.
