Good gaming headphones with mic

[Wedgie]

I'm looking at getting some good gaming headphones with a mic, probably plantronic or sennheiser as they're reputable brands with a good warranty.
Need to buy 2 pairs and would prefer to pay less than $100 for each pair.
Choice of USB with DSP would be good but not a prerequisite.
I'm not after el cheapos as gone through too many of them with poor quality voice input, etc.
Anyone have any experiences or recommendations?
