I just got my "Logitech Mobile Freedom Bluetooth Headset" in the mail a few days ago and I must say that I am very impressed. It fits well and can be very loud. I drive with my windows down on and still don't have it turned all the way up. I am using a LG PM-325 cell phone and everything I have tried so far works. Synced up easily, answers calls, ends calls, and can use the phones voice dial. With the PM-325 if you answer the phone normally you can still easily switch to the headset. I haven't tried it with my computer yet but I have heard it works well.
