I went through 6 different headsets from different companies. Most had a lot of interference; the people I talked to reported difficulty hearing me. Two others quit functioning after a few weeks or kept loosing their bluetooth connectivity.I have had this headset now for 3 months and it works great with my Samsung D807, including the voice dialing and the answer from headset functions.It would be nice if it came with a car charger, but at least always keeps its charge for the day.
