This is a usb wireless headset. just plug it in to your mac or pc and it sees it as another sound device , no drivers needed (xp or os x) I tested it with Skype on the mac and teamspeak on my pc . It comes with a sound api for windows for skype and a few others that allow the buttons on the phone to pickup or hangup calls , I did not try it out because I just like to use apps as is without special add ons ...The range is great , so if you skype and dont want to be tied to your pc then plug this bad boy in and your free to walk all over the house , same goes for teamspeak for the gamers out there.It was so pleasing for something to just work out of the box for a change! I tried for hours to do the same thing using bluetooth and it was a mess... This thing just works!
