The Sony ECM-44B Lavalier Microphone makes the exceptional quality of Sony''s electret condenser microphones available for budget conscious productions, and a variety of sound reinforcement requirements, such as lectures and demonstrations.

To maintain its low cost, this microphone operates on a single AA (does not accept phantom power) battery for over 5000 hours of service.
