Gresch,
I have had many BT headsets.. I use them often. (No I don't wear one as a fashion accessory or in the grocery store...)
But always in my car or at my desk.
Having been through a number of these devices, I have found the best one to be the Motorola's.
I have the H700 and am EXTREMELY fond of it.
It's not too big (doesn't look like a head attachment..) has good battery life, good quality sound, etc.
I believe there are a couple different model numbers for this headset. Depending on what phone you have, you probably want to get a headset that can fit the same car charger and home charger as your cell, so you don't need to buy more equipment.
If you have a RAZR or such, the H700 is the right model.. Otherwise, go to Bestbuy and find this style, motorola, with the corresponding adapter for your current cell phone charger.
