Palm Treo 650 (CDMA)

I like the Moto 850 headset. Had the 810 and didn't like it much, people had a hard time hearing me. I like the design of the 850 how it flips open and activates the BT.

(I use the moto 710 right now, but am getting the Treo very soon.)

Try the Scala 500. I'm sure you will like over any other type of Bluetooth headset. Very small and fits nice on ear.

I have a T650, I have used 3 headsets from Motorola, the HS805, the HS820, and the HS 850. The 805 was nice because it did not need recharged, but the signal quaility was poor. The 820 had decent signal, but the volume was a bit low. I just plain didnt like the 850, it was a little to bulky for me. I also did not like the charger for the Moto headsets, it required that I keep two chargers on the dresser, and two in the car. I have found a decent compromise in the PalmOne treo BT headset. It is very lightweight, has decent signal quality and audio, and best of all, it uses the same charging port as the T650. Although it feels a little cheap, I have been very satisfied with it.
