Speakers with USB output?

[xxWulfyxx]

Anyone know of any PC speakers - basic 2.0 is okay - that have a USB headphone output socket on them?

Basically I have a set of USB headphones and I want a set of speakers where I can just plug in my USB headphones to the front of them to override them to headphone mode.

Doesn't seem like such a big deal really but all I can seem to find are 3.5mm front sockets, not USB.

Thanks

Okay thanks. I've had a good hunt around and can't see anything available. I guess its due to no demand for it.
