One bluetooth headset.
– Headset on cell phone
– Music on Mp3 players (including controls, not just sound)
– Headset on a PC for use with VoIP applications
That’s all. I thought when I bought the Plantronics 590 that I would get most of that. Nope. It doesn’t work with PC’s. Which means I have to have a second headset for VoIP.
Somebody out there (Logitech, Plantronics, etc), do the obvious and make a killing!
