Sony's ECM-77BC is a miniature omni-directional lavalier microphone designed for professional broadcast, sound reinforcement and recording applications. The condenser element features a miniature profile allowing it to be easily concealed in performance and broadcast situations. The omni-directional pattern provides even frequency and sensitivity response at the direct and off-axis sections of the microphone capsule. The ECM-77 provides a wide frequency response of 40Hz - 20kHz. The wide frequency response enables the microphone to accurately reproduce audio signal from a wide variety of sources.
