Has anyone tried TeamTalk out? Supposedly it will allow 4 people to talk and listen when you are on Xbox live. I saw the package in the store and it looks like there is a new adapter that plugs into the controller. It looks like the 3 headsets that are included with TeamTalk plus the original headset plug into the new adapter so everyone can talk. I'm thinking about getting it to try it out, but I wanted to hear some reviews of it first.

Here's a link to some info for it: Link
