The Pyle PMEMS10 headworn omnidirectional mic has a back electret condenser for crystal-clear recording of your voice. It uses a 4-pin mini XLR connector, so it'll work great with your Shure system.

This headset is great, and it sounds just as good as other $300+ headsets from Countryman. Just be careful not to over bend the plastic tube.
