Can a Sennheiser PC 350 use Dolby Digital 7.1 virtual surround sound and how?

I am wondering if a Sennheiser 350 can use Dolby Digital 7.1 virtual surround sound.

It is not said that it supports it, but the Sennheiser 360 uses a special external soundcard which converts the 3.5mm jacks to USB and add 7.1. Since the Sennheiser 360 requires the external soundcard, wouldnt that mean that basically all headsets can use 7.1? But how will that work? Do i need a sound card that supports 7.1? Or will i need a special "normal audio" to 7.1 converter?

    I believe the USB device takes a surround signal (5.1/7.1) then virtualizes it for stereo headphones which are connected directly to the USB device via a 3.5mm jack.

    *You can NOT get a proper surround signal from a 3.5mm jack as that only contains stereo data.

    So, provided the USB device does what I think, then any set of stereo headphones could be plugged in to it and have virtual surround sound.

    ASUS has a new Z97 motherboard (hero VIII?) that has an onboard audio feature that can do real-time virtualization that is output to the Front Panel of the case and works with STEREO headphones.

    So again:
    1) 5.1/7.1 signal ->

    2) Signal virtualized by USB device then converted to analog ->

    3) 3.5mm stereo headphones experience Surround Sound
  2. So basically it is possible? Just not true 7.1/ 5.1?
