Sony ECM88B

The Sony ECM-88B is an ultra-miniature, omni-directional electret condenser lavalier microphone designed for applications demanding pristine audio quality and minimal visual intrusion. Tailored for studio broadcasting and professional video production, it features a sophisticated dual-diaphragm design that enhances sensitivity, expands dynamic range, and minimizes inherent noise. With a flat, extended frequency response from 20 Hz to 20 kHz, the ECM-88B captures voices and instruments with exceptional clarity and naturalness, making it ideal for high-stakes media environments.

This microphone is built to endure varied shooting conditions, featuring a water-resistant construction that ensures consistent performance even in challenging environments. A unique diaphragm mounting structure significantly reduces cable noise-a common issue in lavalier setups-allowing for cleaner recordings in movement-intensive scenarios. The ECM-88B includes a DC-78 power supply unit, which supports both phantom power and AA battery operation, offering flexibility in field and studio setups.

Despite its rugged capabilities, the ECM-88B remains remarkably compact. The microphone head measures just 3.5 mm in diameter and 16.8 mm in length, making it one of the smallest in its class. Its feather-light build-less than 1 gram-ensures comfort and invisibility when worn. The included accessories, such as tie clips, a windscreen, and a mic case, further support diverse mounting and handling needs. Whether mounted discreetly on clothing or integrated into a headset, this microphone delivers consistent, high-quality audio ideal for broadcast, stage, and corporate use.
