More sensitive than a Dynamic microphone, a condenser microphone uses a small amount of electricity to suspend a diaphragm. Sound waves hit and vibrate the diaphragm producing a fluctuation that can be transformed into an audio signal. All condenser microphones need what's known as "phantom power" to run. Condenser microphones tend to have a noticeably higher and more flat frequency response than dynamic microphones. Condenser microphones are more sensitive on the frequency spectrum, and have a wider dynamic range.
