First of all, when you get randomly disconnected it's xbox live, not the mic. It happens all the time, even if you have a wireless mic, especially in xbox live parties.
It's nothing to do with the mic, one thing I would like improved with the microphone is to be a little bit more voice sensitive, sometime I feel I have to shout / raise my voice for people to hear me properly. Everything else with the mic is fine, apart from the fact it's easy to break.
But if you look after your things, should be fine.
