Dont be fooled by the Playstation 2 in the title, this headset will work brilliantly in all USB applications, I use this headset for both PS3 online gaming and for ichat calls on the mac. It performs great for both.
The headset itself is very comfortable to wear and use, the rotating microphone arm allows you to push it up out of the way when not needed and the adjustable arms mean after a few minutes I forget i'm wearing it.
Sounds through the earpiece is clear and loud, when used with the PS3, only chat sounds are transmitted (no in game audio) so the lack of stereo speakers isn't a big deal.
And on to the most important point, the noise cancelling. My setup for gaming is in the same room as the main TV so its essential to me that my mic only picks up what I say, the background cancelling functions very well and allows noise free gaming for my friends.
Build quality is pretty good. I've thrown mine around allot and the main wire has come free from its housing, but everything still works well, I would advise using a USB extension to avoid accidentally pulling on the wire when you forget your wearing it.
