Recommendation for a headset with a microphone for recording

Hi, I wonder if anyone would be able to recommend a headset I could purchase to use when I record my presentations in Articulate. I do not have a particularly quiet environment and would prefer to wear a headset leaving my hands free while I am recording.

I would like one that has a USB connection and works in Windows 7 - soon to be Windows 8!.

Any recommendations would be much appreciated.

Thanks,

Jane
