This is my headset and I LOVE it. It has all the features you want as well as the detachable mic. These are the most comfortable headsets I’ve ever worn. It’s right at $70 and looks like shipping is just $4.09. When I checked the circuit city website it looks like they only charge $2.99 shipping.
There is a similar cheaper one here: http://www.amazon.com/Creative-Labs-51MZ0310AA005-Fatal1ty-Headset/dp/B002DS4HTM/ref=sr_1_1?ie=UTF8&qid=1305431121&sr=8-1
I have never tried this one but I think the only difference is the sound blaster.
