The Sony ECM-C115 is a miniature omnidirectional lavalier microphone designed for hands free audio capturing of lectures, performances, ambiance and more. The omnidirectional polar pattern yields a generous pick up at the front and off-axis sections of the capsule. The wide frequency response and sensitive electret condenser capsule result in pristine audio reproduction with low noise floor. The attached cable features a gold plated 1/8" mini connection and an approximate length of 1m (39 3/8 in.). The connection is compatible with most MiniDisc recorders and other consumer input devices. The microphone includes the battery box, holder clip and windscreen.
