Sony's electret condenser microphones available for budget-conscious
productions, and a variety of sound-reinforcement requirements, such as lectures
and demonstrations. Measuring only 8.5 x 14.5mm, the ECM-44B reduces the visual
distraction for the audience. The ECM-44B can be depended upon for clean,
bright, yet natural reproduction. To maintain its low cost, this microphone
operates on a single AA (does not accept phantom power) battery for over 5000
