Our priest uses what we call a "Madonna mike" - it hangs on his ear and loops around to a spot in front of his mouth. We switched him from a clip-on cardioid mike because the rustling of his vestments in the microphone was driving the congregation batty. I can't get him to use a pop shield because he thinks it makes the microphone too visible. But he has a tendency to nod off when he doesn't have a speaking part. I think a pop shield would mute his snoring a bit, but I may never get the chance to experiment to see if my theory works...
