Sony ECM-W5 – High-Resolution Wireless Microphone System for Video and Live Streaming

Professional wireless audio for demanding creators

The Sony ECM-W5 is a compact, versatile wireless microphone system developed for professional videographers, journalists, content creators, vloggers, and live-streaming professionals.

Featuring two microphone transmitters and a dedicated wireless receiver, the system allows two speakers to be recorded simultaneously with excellent audio quality and outstanding freedom of movement.

Designed primarily for Sony cameras equipped with a compatible digital Multi Interface (MI) Shoe, the ECM-W5 provides direct digital audio integration without requiring an additional audio cable.

The system can also be used with compatible computers, smartphones, and other recording devices, making it suitable for interviews, documentaries, news reporting, audiovisual production, and live broadcasting.

High-resolution audio recording up to 96 kHz/24-bit

Capture every detail with exceptional clarity

The Sony ECM-W5 supports high-resolution digital audio recording at sampling rates of up to 96 kHz/24-bit, delivering detailed and natural voice reproduction.

With compatible Sony cameras, the system also supports 48 kHz/32-bit float audio recording.

This advanced recording format provides extensive flexibility during postproduction, allowing quiet passages to be adjusted and reducing the risk of digital clipping caused by sudden changes in volume.

On supported cameras, 32-bit float audio can be recorded directly into the video file, eliminating the need to synchronize a separate audio recording during editing.

Precise audio level control

The ECM-W5 provides comprehensive audio adjustment options:

• Automatic gain adjustment to help prevent clipping and distortion.

• Manual gain adjustment from -12 to +12 dB.

• Noise Cut function for reducing unwanted background noise.

• Low Cut filter for minimizing low-frequency disturbances.

• Gain adjustment available during 32-bit float recording.

These functions allow operators to adapt the system to different recording environments and production requirements.

Reliable wireless transmission up to 500 metres

Outstanding freedom of movement

The Sony ECM-W5 offers wireless transmission over distances of up to 500 metres (1,640 feet) in line-of-sight conditions.

Its optimized wireless communication system uses Bluetooth frequency-hopping technology to maintain a stable connection and reduce audio dropouts, even in crowded wireless environments.

Low-latency transmission makes the ECM-W5 particularly suitable for interviews, presentations, field reporting, and live streaming.

Actual wireless performance depends on environmental conditions, obstacles, and radio interference.

Built-in backup recording with 64GB per transmitter

Protect every important recording

Each Sony ECM-W5 microphone transmitter features 64GB of built-in storage for independent audio recording and backup.

This provides valuable protection against potential wireless interruptions or recording problems with the main camera.

Recorded files can be transferred to a computer via USB-C, either directly from the microphones or through the included charging case.

Compatible Sony cameras also support simultaneous WAV recording, allowing a separate audio source to be retained independently from the video file.

Timecode synchronization for efficient editing

The ECM-W5 includes timecode synchronization functionality to simplify audio and video alignment in postproduction.

In USB SYNC mode, the receiver connects to a compatible Sony camera through USB-C to synchronize timecode information with the camera's video metadata.

This feature is particularly useful for multicamera productions, professional interviews, and complex editing workflows.

Expandable wireless system with up to four audio channels

Record up to four speakers simultaneously

The Sony ECM-W5 kit includes two microphone transmitters but supports expansion to four simultaneous transmitters.

By adding two optional Sony ECM-W5T transmitters, users can record up to four speakers simultaneously.

Compatible Sony cameras can record the different audio sources on separate tracks, providing greater control during mixing and postproduction.

This expandable design makes the ECM-W5 suitable for both individual creators and small professional production teams.

Wireless audio monitoring with Bluetooth LE Audio

Monitor your recordings without cables

The Sony ECM-W5 supports wireless audio monitoring through compatible Sony Bluetooth LE Audio headphones.

This feature allows users to check audio quality without a physical headphone cable, improving convenience and freedom of movement.

The receiver can also capture audio from microphones built into selected compatible Sony wireless headphones.

This provides a lightweight recording solution for vlogging, mobile reporting, and direct-to-camera presentations.

With compatible devices, the system also supports binaural recording to capture environmental sound with a natural sense of spatial depth.

External microphone inputs and flexible mounting

Compatible with external lavalier microphones

Both the microphone transmitters and the receiver provide 3.5 mm external microphone inputs.

These connections allow external microphones, including optional lavalier models such as the Sony ECM-L1, to be used when required.

Each transmitter features a locking 3.5 mm TRS connector to minimize accidental disconnection during filming.

Compact design and versatile attachment

The microphone transmitters can be attached to clothing using their integrated clips or the included magnetic mounting accessories.

Their discreet design makes them suitable for on-camera appearances, interviews, presentations, and professional video productions.

The upright form factor also allows convenient handheld operation for reporting and spontaneous interviews.

Seamless integration with Sony cameras, computers, and smartphones

Direct digital connection through the MI Shoe

When used with a compatible Sony camera, the receiver connects directly to the Multi Interface Shoe.

This provides several advantages:

• Direct digital audio transmission to the camera.

• Cable-free audio recording.

• Receiver power supplied by the camera.

• Direct integration of 32-bit float audio into video files on supported models.

• Camera-linked power control, depending on settings and compatibility.

Versatile USB-C connectivity

The Sony ECM-W5 can also be used with compatible computers and smartphones.

The included USB-C adapter enables convenient connection to devices supporting USB Audio Class 2.0, including support for 32-bit float recording where the connected hardware and software allow it.

This versatility makes the ECM-W5 suitable for a wide range of recording environments.

AMOLED touchscreen and intuitive controls

Fast access to essential settings

The receiver features a high-contrast AMOLED touchscreen, complemented by a physical control wheel and button.

This interface provides quick access to audio settings, gain adjustment, and system configuration.

Dedicated LED indicators clearly display:

• Power status.

• Recording status.

• Wireless connection status.

The transmitters also provide convenient control over internal recording start and stop operations.

Extended battery life and included charging case

Up to 11 hours of operation

The Sony ECM-W5 includes a compact charging case that simplifies transportation, storage, and charging.

Opening the charging case places the receiver in standby, while removing the components powers them on for operation.

When connected to a compatible Sony camera through the MI Shoe, the receiver can be powered directly by the camera, preserving its internal battery.

Depending on operating conditions:

• The receiver provides up to 7 hours of standalone operation.

• The microphones offer up to 7 hours of continuous use under the specified system conditions.

• Total operating time can reach up to 11 hours when using the charging case and camera-powered receiver.

Actual battery performance varies according to settings and operating conditions.

Lightweight construction and environmental considerations

Each microphone transmitter weighs approximately 27.1 g, while the receiver weighs just 35 g.

This lightweight construction makes the system ideal for mobile video production and extended recording sessions.

Sony also incorporates recycled materials representing more than 41% of the main unit's plastic weight, supporting its wider environmental initiatives.
