Headset work right away, intuitively easy to use. Is immediately both from the phone (Sony Experia E1) as well as netbook (Samsung Endi) recognized. With small plastic strap is the ear hardly noticing. Weight sensationally low. Drawback: The temple is unfortunately already broken (connection clip to the device), now must be found which handmade things, that's too bad ... why only three stars. The basic idea of the device + bracket for sports etc unbeatable.
