AFAIK, this is not possible with the current Android Operating systems, however it might be possible with future platforms supporting the new Android Open Accessory support.
edit : As for connecting a standard 3.5mm jack, you should be able to do this if you bypass the USB sound card part and connect it directly to the wires coming out of the headphones. But depending on the headphones the USB soundcard circuitry (where the signal is converted from Digital to Analog) could be inside the headphones, somewhere in the middle of the cable or in the USB plug itself; you have to figure out where it is and attach the audio jack to the wires after the soundcard (where the signal is analog).
