Design and Build
The Sony ECM-W3 Wireless Microphone system comes in a compact and portable design suitable for content creators, interviews, and video production. It includes a receiver, microphone units, and a charging case, all finished in black. The receiver measures 32 × 29 × 50 mm and weighs about 25 g, making it easy to mount on a camera. The charging case measures 92.5 × 41.5 × 65.5 mm and weighs around 110 g, providing safe storage and charging for the microphone components.

Audio Performance
The ECM-W3 uses MEMS microphones with beamforming technology to help reduce background noise and capture clearer voice recordings. It offers a frequency response range from 100 Hz to 10 kHz and a front sensitivity of –20 dBFS at 1 kHz. The microphone maintains low intrinsic noise levels of 16 dB SPL or less and can handle sound pressure levels up to 120 dB SPL. With a dynamic range of 104 dB or more, the microphone system is capable of delivering detailed and balanced audio during recordings.

Connectivity and Power
The system supports Bluetooth 5.3 wireless communication with LC3plus codec and has a working range of up to 150 meters. The receiver includes a 3.5 mm stereo mini jack and a USB Type-C port for flexible connectivity with cameras and other devices. Both the receiver and microphones use built-in lithium-ion batteries and take about 2 hours to fully charge. The charging case includes a battery capacity of around 850–950 mAh, while the earbuds have 77 mAh batteries. A quick 10-minute charge can provide approximately 1 hour of music playback time.
