The two most important mic categories you’ll want to get acquainted with are dynamic and condenser. Though there are always exceptions, you can chart the differences between them in a few key ways. Dynamics are well-suited to handling loud sounds; condensers are more sensitive to the nuances of quiet sounds. Dynamics require no power source to operate; condensers run on Phantom Power, a feature that comes standard on nearly all home-recording audio interfaces. Dynamics tend to be more rugged; condensers more fragile. Finally, dynamics tend to be cheaper; condensers more expensive.
