Coordinating a large number is difficult enough as it is, I can imagine that it get ten times as worse if they can’t hear you, so if you’re in that line of business you could carry a Mini Megaphone around and save yourself a lot of trouble. It’s not exactly small enough to fit in a pocket, but its size (5″L X 3¼”Dia) makes it slip inside a bag with no problems.

One of the other suggested uses is for sporting events… but please think of the people around you. Would you like a guy with a megaphone yelling in your ear? Didn’t think so. So only get this if you need it, most people don’t go to watch sports to end up with a headache.
