I have purchased bluetooth headsets in the past but never was satisfied with the fit of the ear piece and there were always connection problems. Since I only use the bluetooth in my car I went with the T305 this time. I am very pleased with the quality of sound and it always connects to my nokia phone. The only down side is that it will stay connected in my home when the car is in the driveway so I have to remember to turn it off when I get home.
