Sony ECM-90 Electret Condenser Lavalier Microphone

The Sony ECM-90 Electret Condenser Microphone is an ultra-compact, dual-diaphragm omnidirectional microphone capsule designed for quality-critical applications in ENG, Studio, EFP, and Location Sound applications.

The ECM-90 has a flat-and-wide frequency response of 20 Hz to 20 kHz, a dual-diaphragm mechanism that reduces the cable noise and a splash-proof design built to withstand every-day use.

The ECM-90 is water resistant design maintaining sound clarity in almost any application or environment and is shielded for use with digital wireless transmitters.


  • 3.5mm Subminiature, Omnidirectional Capsule, the smallest offering from Sony for wireless use.
  • Dual Diaphragm Technology, with near-silent cable handling.
  • No-nonsense accessories, with a windshield and the usual selection of intuitive Sony clips included in the box.

The ECM-90 is available with two different connectors:

  • ECM-90BC - Sony 4-pin (SMC9-4P) connector
  • ECM-90LM - 3-pin Lemo connector
