I have been using my Moto HS850 & HT820. The HS850 is nice for a quick earpiece... I love using my HT820 while listening to my 4GB of stereo tunes on the MiniSD, then it automatically pauses when a call comes in.
Granted - I look like a StarWars character with my shaved head and the BT behind-the-neck headphones - but nobody's rockin' like I am - particularly at work!
---UPDATED---
I can't wait to get the S9 headphones to use as my primary, relegating the HT820 for backup work. I won't look like such a dork driving home with that big old headset on
