Plantronics 655 headset

After trying the Motorola bluetooth headset, I decided that I needed something of better quality as I use my Blackberry as a phone for work. The Motorola did not fit well, had weak volume, and poor reception on the end of the listener.
The Plantronics 655 however is great. The volume is crystal clear and very loud. Clients and friends often say that they can not tell I'm using a headset. The earbuds fit so much better than the traditional earhook are really comfortable (I wear mine all day as I travel for a sales job). The pocket holster is invaluable for easy transition from ear to jacket/shirt.
Downsides, with my blackberry the reception is only clear when the headset is within say 2-3ft from the blackberry. After that it gets noisy. There is a 1-2second delay in the headset from when you answer til the call is connected to the headset.
