The Sony ECM-CS3 microphone has a clip-on design for hands-free recording, and it rotates for flexible placement and clear digital voice recording. The condenser lavaliere device includes a 39-inch cord, and features an omnidirectional polar pattern that picks up sound clearly from around the room. A 50 Hz-15 kHz frequency response guarantees a reliable and clear sound reproduction, while a gold-plated L-shaped mini plug ensures high signal integrity. The unit is compatible with most DVRs and computers, so you can use it with equipment you already own. Make videos, record lectures, and much more.
