When we added on-screen hymn lyrics to the Mass at St. Mary's Church, my duties as choir singer and sound engineer suddenly included PowerPoint projectionist. I need a microphone that does its job without getting in the way, but it also has to be where I need it when I turn my attention from the audio mixer to the computer. Since I sit right next to the gear, we didn't need the expense of a wireless system (along with its appetite for batteries), and even a wired condenser headset mic was out of the question, budget-wise. For the money, the Shure WH20XLR is a gift from audio heaven.
