Condenser microphones are one of the most popular mic choices for studio recording applications because of their sensitivity and fidelity. In general, a condenser microphone will provide a wider frequency response range than their dynamic microphone cousins, but will have a lower input sensitivity. In other words, they’ll pick up more of the input signal faster. This means that most condenser microphones (with some exceptions) are better suited for quieter environments, like one afforded by a studio.
