Lavalier mic with excellent sound quality, ideal for use with DWT-B03R wireless transmitter:
The Sony ECM-77 miniature lavalier 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 optimized for clear speech pick-up, with an extended frequency response, impressive sensitivity, and low handling noise.

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