Can the sennheiser 350SE or 363D work with an onboard sound card?

[hellraider3774]

I was looking into upgrading to a new headset, possibly the sennheiser 350SE or 363D but I only have onboard sound (i7-2670QM). I am wondering if I will be able to use either of these headsets without an actual sound card? Would an external sound card suffice?

onboard sound cards should support mic and headphones. so it should work.

The selling point of the 363d over the 360 is that it comes with a USB sound card.
