For my DECT phone I was long looking for a headset. Too expensive, it should not be. Eventually I found this and ordered it. It lies easily login as an additional handset to my phone Gigaset A400. Incoming calls I could immediately answer using the headset. With the outgoing I did hard me, but closer study the owner's manual of the phone also made it in the end without problems. Since then, I make phone calls almost entirely with headset and am extremely satisfied! Callers are well understood and they understand me well. I have hands free and pay now much better than in the time "before the headset". The headset sits well in the ear, even without strap holds it. The one must always only a little fumble around the ear until it is seated properly, but that could be ear-dependent. When comparing how expensive other headsets, one wonders what can the more? This my claims here is enough to 100 percent!
