Sony ECM-W2BT Camera-Mount Wireless Microphone System for Sony Cameras

Overview

The Sony ECM-W2BT Camera-Mount Wireless Microphone System delivers high-quality, low-latency audio for vloggers, YouTubers, journalists, and content creators using Sony cameras with MI interfaces. This true-wireless microphone system features advanced Bluetooth technology for stable, interference-free audio, making it ideal for interviews, dialogue, and video production.

Its miniature clip-on transmitter has a built-in omnidirectional microphone for quick, cable-free setup, while a 3.5mm input allows the use of a smaller lavalier mic like the ECM-LV1 (sold separately). The compact receiver mounts directly to the camera's MI shoe, providing up to 9 hours of recording with camera power or 3 hours with built-in batteries.

Fast and Easy Wireless Audio

The ECM-W2BT’s built-in omnidirectional microphone captures clean, natural sound from all directions, making it ideal for on-the-go vlogging and interviews. The Qualcomm aptX Low-Latency Bluetooth ensures the audio stays synchronized with video, while suppressing extraneous noise for consistently clear recordings.

Cable-Free MI Digital Connection

Directly mounting the receiver to a Sony MI shoe powers the unit and allows up to 9 hours of recording, while cameras with a digital interface capture pristine, low-noise sound. When used without MI power, the built-in batteries provide up to 3 hours of standalone operation, keeping you mobile without cables.

Adjustable Input Levels and Windscreen

The ECM-W2BT includes a sophisticated attenuator function that lets you reduce loud sounds or amplify quieter sources for optimal recording levels. The supplied windscreen effectively minimizes wind and breath noise, ensuring clear, stable audio even during outdoor shoots.

Stable, Uninterrupted Audio Recording

With reliable wireless performance, the ECM-W2BT reduces the risk of audio dropouts, even in environments crowded with wireless devices. The system supports a 200 m / 656' operating distance, providing freedom to move without worrying about signal interruptions.

Convenient Modes for Single- and Two-Person Shoots

The receiver offers three pickup modes: microphone only, receiver only, or a MIX mode that captures both simultaneously. This flexibility allows one operator to record both themselves and a subject, while MIX mode is perfect for interviews or multi-person recordings.

3.5mm Input for Smaller Lav Mic Option

The 3.5mm input lets you connect a smaller lavalier, like the ECM-LV1, for a discreet, up-close audio source. This audio is then transmitted wirelessly across the full operating range, giving you a professional, cable-free setup without compromising sound quality.

Tough, Compact, and Lightweight Design

The ECM-W2BT is dust- and moisture-resistant, ready for reliable outdoor use. Its small size and lightweight construction—28 g for the receiver and 27 g for the transmitter—ensure that it won’t slow you down during shoots, making it perfect for mobile or location-based recording.

Use with a Wide Range of Devices

Beyond Sony cameras, the 3.5mm TRS output allows connection to PCs, digital voice recorders, and other cameras without MI shoes, offering versatile use across multiple setups and recording environments.

Safeguards to Prevent Recording Failures

Built-in display lamps provide visual feedback: the LINK lamp confirms successful transmission between transmitter and receiver, while the POWER lamp warns of low battery, helping prevent unexpected interruptions during recording.
