Headphones Question from an Audio IDIOT

[scdavis0]

I know very little about audio, PC or otherwise. I am considering using headphones as a primary listening device. Generally speaking, for things like Dolby Prologic and Dolby Digital to work, do both my sound card and output have to support these standards. Will headphones support Dolby Prologic? Dolby Digital? Is there such thing as speakers "supporting" these standards, or is it just the sound card/receiver?

If you think that the answer is a resounding no, then take a look at this:

To me, it seems that the Dolby Pro Logic capability of the provided DSP could be replaced by the DSP on a soundblater live card. Either way, it seems that the headphones DO support Dolby Pro Logic. Also, look at:

Click on the DSP 360. This product almost seems to imply that the DSP will make ANY headphones use Dolby Pro Logic.

Still confused...

If your soundcard puts out a Dolby Prologic output, then you can have Dolby Surround Sound if you have the appropriate decoding device (whether it's built into the headphones/control thing/receiever/whatever).

I dunno if any sound card will output a Dolby Prologic signal though.

I thought that the new Creative 5.1 would output not only prologic, but dolby digital?
