Oh dear... I have only used the mic a few brief times.
As a normally quiet person, not really looking forward to using the mic for all these games to be honest as I don't really know what to say to the other person and can't help but feel it'll be like those awkward moments of silence in a lift with strangers...
So, as much as I'm not looking forward to it I respect the decision to use them and will give it a go but I apologise if I in advance if I don't say much (and I'm not sure if I'll be able to refrain from a bit of swearing if the kids aren't in earshot..)
So, you'll probably get a "hello", "good game", "good play", and the occaisional "what the f**k just happened..."
Mind you, my headset is just the standard one that comes with the xbox360 and I've never used this one. The other one I had access to broke recently. So I hope this one does the job.
