I'm very happy with the headset after I read the instructions properly was also connect the phone ot no longer a problem. Calls is entgegennohmen after less time no more difficult (at first not respond to two times until the party hears). Sound quality I find okay. The only disadvantage (problem) when the headset is conveyed in your pocket (you will not always have what in the ear) is selected the last number dialed often because it has come to the button maybe times. There's what would have to be invented. But otherwise great.
