The C420 is a cardioid condenser head-worn microphone with behind-the-neck headband, external shock mount for high mechanical-noise rejection and a miniature gooseneck for precise positioning near the user's mouth. Providing a full frequency response bandwidth, the C420 is ideal for solo vocalists, singing keyboardists, drummers, guitarists, dancers, and other performers that require a mobile, handsfree solution.

The C420 has a fully adjustable behind-the neck steel headband and adjustable ear pieces for a comfortable and secure fit. The cable exiting from the rear of the headband helps in concealing wires and provides a more direct connection to a bodypack transmitter.
