Condenser microphones require power from a battery or
external source. The resulting audio signal is stronger signal than that from a
dynamic. Condensers also tend to be more sensitive and responsive than
dynamics, making them well-suited to capturing subtle nuances in a sound. They
are not ideal for high-volume work, as their sensitivity makes them prone to
distort.
