I'm using a Plantronics headset w/mic that uses 3.5 male jack.
I have the mic cable plugged into the \"mic\" port on the back of the computer and the other cable on the headset I ran up to my desk. I can either listen threw the speakers or I can plug the cable into my speakers so I can listen threw the headset and cuts off the speakers.
That would be a yes to both. I would like to be able to do either which I can do with my present setup. Would like to go to USB for better overall performance.
