Although works but you do not understand me

Recently I've bought this headset because I wanted to try it a try as it is to telephone with headset. I can not Wieterempfehlen because it simply takes too much background noise. For a little more money, you get a headset that filters out background noise, making it to use in the car and on the street outside. If you go to this part of town you, your interlocutor understands almost nothing. Advantage is that it can be linked easily with the mobile phone and the connection also remains stable.
