Which surround sound headphones?

[SnipaMasta]

My Medusa's are slowly breaking and the speedlink hub has gone after about 2 years of constant use, so I'm looking for a replacement. I've seen some "Steelsound" ones on OC but I'm not sure whether they allow me to plug in both my speakers and the headset, so I'm wondering if anyone can reccomend some surround sound headsets that allow me to do this (except the default medusas).

Thanks.
