Gaming Headset or Headphones with clip on mic?

So im trying to decide between getting the Sennheiser PC 350/360 or getting a HD555 and a clip on mic. What are the pros and cons of both, and if I do go with the HD 555 whats a good clip on mic that would give crystal clear voice?

well they're both sennheiser, I heard that the HD555s have better quality audio, but would any clip on mic be as good has having a the headset?

I have those look at them, they are the best! that and the ZALMAN MIC-1

I have the Sennheiser PC 350 and its a really nice headset. Of course, I'm not an audiophile of any sort. Still, the headset does what I need it too for games like Borderlands, BC2, and many of my other games.

Ill be using it mainly for gaming and blu ray movies, not much of a music listener but when I do it's just basic mp3s
