Bluetooth headset compatible with Windows 7?

[t]

I'm looking for a bluetooth headset that would be compatible with both my cellphone (which would take just about any headset) and my laptop, which is running Windows 7 Home Premium with a USB bluetooth dongle.

I tend to do a lot of talking over voice chat on my laptop, like over IM services, and would like to have a wireless headset so I can move more freely around my office, and having a headset for my laptop that would double up with my phone would be a great bonus.

I haven't been able to find much info on the web on this topic, and the headset I already own, a Motorola H375 which I got free with my phone, only works for telephony with my laptop. Any suggestions?
I switched to Microsoft's Bluetooth stack, still no luck.
