Yeah Frior, that's how I was doing it before when using the lightweight headset with the round peg style plugs. Except I didn't even need the splitter because my laptop has 1 mic. & 2 headphone plug-ins for those type.
When I got TIR I also got a new headset that the Pro Clip would work with (it wouldn't clip to the flimsy one I had been using), but the new headset has a usb plug and when I plug it in, the round jacks stop working. So I'm starting to think she's out of luck unless I can plug two usb headsets in at the same time. Anyone know the answer to that before I waste my money getting her some new headphones?
