The class on a limited budget

I do not much like Bluetooth headsets ... Wearing glasses, they often injure myself by hanging around the wrong branch: this is not the case of the latter, including the clip seems particularly well studied .
I own a 4S iPhone: instant startup, there is nothing to do but to pair the device for the first time via Bluetooth settings (no password, no) and then it just works, with a bonus tiny pictogram on the screen that provides information about the battery level of the headset. An English female voice warns: "connected".
His side is excellent, it is at Sennheiser. Listen to the radio or bike ride becomes a real pleasure, without isolation from the outside world. The buttons on / off, volume and communication jack are accessible and easy to use, a little flat on the volume, a little firm, but that is a negligible detail. The microphone seems excellent bill, if I believe my correspondents. For cons, the application "voice recorder" did not take into account, unless I missed something, and it's a shame for taking voice notes ...
Last thing: the device recharges via a mini-USB cable fairly stiff wire to support light weight of the machine during operation, and it is very convenient (standard mini-usb socket). Overall very positive. I adopted.
