I heard that if I use a headset on a system without a sound card or a disabled sound card it will still work. Meaning that I can hear sound and speak to users through a VoIP service such as Skype.

Is this true? Or did I mis-interpret wrongly?

From this forum thread:

USB headsets basically have a USB sound "card" integrated. For the Logi USB headsets that's a small unit integrated with the cord. You could pull your soundcard out of your PC and the USB headset will still give you sound.

Which makes sense.

Yes, USB headsets are separate audio devices and work independently from built-in sound cards.

VoIP applications such as Skype let you choose your preferred audio device if more than one audio device is installed:

That is true! Just make sure if you remove the headset that the computer selects the correct card. I haven't figure out why but after I remove my MS lifechat headset. Windows 7 always defaults to the SPDIF out. – Kelbizzle Jan 27 '10 at 23:08
