Product Information

Sony ECM-77LM Miniature Omni-Directional Microphone

Lavalier mic with excellent sound quality

The Sony ECM-77 miniature lapel microphone is seen in daily use on TV shows around the world, and is an equally familiar sight in both studio-based productions and on location.

A discreet 'hands-free' alternative to handheld microphones, its popularity is due to a combination of excellent sound quality, robust construction and an attractive cosmetic design. The miniature design of the ECM-77 makes it easy to conceal in a stage performer's costume.

The electret condenser microphone's omni-directional capsule is optimised for clear speech pick-up, with an extended frequency response, impressive sensitivity and low handling noise.

Featuring a small 3-pin connector, this ECM-77LM version is an ideal partner for use with the DWT-B03R DWX Series digital wireless microphone bodypack transmitter.
