Gents let me just say that not only do they kick a** for gaming but for sitting around listening to some Led Zeppelin on the CD player; they are awesome. My wife thinks it is sort of funny to see me sitting there reading with a microphone sticking straight up but they are a real nice fit. A little pricy at $99 plus shipping from
PCMALL.com.
I forgot to add that if you don't have a soundcard the USB function allows you to use the soundchip on the USB dongle that comes with the headphones and it works nicely for music as I found out today at work. Also the two plugs for microphone and headphone that attach the dongle to the headset work equally well without the USB dongle for attachment to your soundcard. The music quality is very nice and allows you to hear a wide range of the sounds in music and games.
Here is a link to a picture of the headset from Sennheiser's site.
