As others have said, the functionality of this headset is very good. The biggest bonus to me is that it handles the Palm Treo's marginal Bluetooth quite well. My Plantronics Discovery 640 had great sound, mic, and fit, but would always (I mean literally 100% of the time) drop the BT connection about 1 minute after ending a phone call on my Treo 700p and I'd have to reconnect. Even though I am quite sure it is the Treo's fault, I'd rather spend $50 for a new headset than $400 for a new smartphone. With the WEP200, it stays connected all day after many calls.
