Good Streaming Headsets?

Me and my friend are trying to start streaming and we got a Blue Yeti USB mic. But we both either have to be right on top of it or settle for an extreme amount of background noise. So we were thinking headsets would be a better way to go. But we have no idea what to look for. Any advice? Whats the best bang for your buck?

The Blue Snowball (not the Snowball Ice) has a great microphone for accepting and isolating sound from more than one angle, and also has the ability to be switched if you want it to be just for the one of you talking directly into it.
