I've got a wirevo bluetooth stereo headset...
...that I usually use with a broadcom (iogear) usb bluetooth adapter. If your pc has bluetooth built-in, make sure it supports bluetooth stereo audio profiles (might be advanced audio profile, or something similar). You might need to upgrade your bluetooth drivers and software. I've used mine on dozens of laptops, pc's, and phones and rarely had any problems. You may have to manually switch between regular bluetooth audio (as in 2-way, microphone with single audio channel) and stereo audio.
What might be nice is a PDA with USB for...
Use with a USB microphone.
I use a Plantronics USB headset for voice recording, and a Roland UA-3 for line-level stereo input with my Vaio.
