The BlueAnt Z9i has got to be the best bluetooth headset on the market. I have had "14" different headsets over the last couple years Including Jabra, Jawbone II, Motorola, and plantroinics just to name a few. The Z9i is the best one I have used. It is the clearest and easiest to use. The people on the other side of the call can hear me perfectly clear even rideing in a car with the window down. I use the Z9i with a Palm treo 700w right now. But as we all know the BB Storm is coming out this friday so I will be switching. I'll let you know how the BlueAnt works with the Storm as soon as I get it.....Thanks all who read this and I hope it helps.
