Although I can’t remember that last time I’ve used a computer that didn’t have at least on-board sound, the addition of built-in PC audio hardware to the Platronics USB DSP-500 headset is an interesting twist. Still, unless you want to use the DSP-500 as your only sound source, a regular sound card or USB audio device (like the Creative Extigy or Griffin iMic) would probably offer much more all-around functionality. Also, could someone tell that woman not to scream so loudly into the monitor? It scares the pixels.
