OP, when you are looking for something specific, you need to say so. By default, a "headset with a microphone" will not sport a USB interface. There's a link to a used one from EBgames; apply the CAG15, SAVER, and Edge card code if you have one, and it should bring it down to a sufficiently cheap price. Keep in mind that it's a used headset, however, so be prepared to make a run down to your local brick & mortar store if it turns out to be glitchy. The only sticky point is that it doesn't explicitely say that it has a microphone. What can I tell ya...the playstation2 one does.
