Sony ECM-90BC Electret Condenser Microphone

Sony ECM-90BC (ECM/90BC, ECM_90BC, ECM 90BC, ECM90BC, ecm-90bc) Electret Condenser Microphone

Ultra-miniature, omni-directional electret condenser lavalier microphone designed for quality-critical applications in ENG, Studio, EFP, and Location Sound applications. Dual diaphragm design contributes to high sensitivity, wide dynamic range, and low noise.

Flat and wide frequency response (20Hz – 20kHz) provides natural sound reproduction. Water resistant design maintains sound clarity in almost any application or environment. Shielded for use with digital wireless transmitters.
