I have had a Plantronics Explorer 330 headset for about a year and it has been a great addition to my Treo 750, I use it alot at work with a program called BTAudio and I listen to music most of my busy day without even looking out of place or causing a disturbance. I recently picked up a laptop (Thinkpad T61) and I wanted to know if I can use that headset to pair with my laptop and listen to audio from that while traveling and also use my phone, or do I have to go back and forth with my pairing on the devices? I looked on Plantronic's site but couldnt find how many devices I could pair with. Ideally I would like to be able to use it for hands-free and audio at work with my Treo and at home for listening to webcasts, etc. from my laptop.

Is this possible?
