Ideal for business meetings ... Sony Business Microphones use advanced noise reduction to separate voices from background sounds, and a mode position switch that optimizes performance in large or small rooms. For stereo microphone applications, check out the Sony ECM-ZS90. Ideal for music recording, it can also be switched to a super directional mode for recording in large lecture halls. The ECM-ZS90 mic is ideal for digital recording as well. Another microphone great for lecture or speech recording is the Sony ECM-Z60 super zoom directional microphone.
