Sony Electronics Introduces the ECM-W5 Wireless Microphone with High-Resolution Audio Recording and Stable Connectivity

Direct-to-camera 32bit float audio recording¹ and wireless monitoring² help streamline production workflows

SAN DIEGO, Oct. 14, 2026 /PRNewswire/ -- Sony Electronics introduces the ECM-W5 wireless microphone for video creators, combining high-quality audio capture, stable wireless transmission, and versatile recording features to support a more flexible production workflow across a wide range of shooting scenarios.

The system pairs two transmitters with one receiver. It transmits over a line-of-sight distance of up to 500 m³ and is designed to reduce audio dropouts in congested radio-frequency environments. Through the Multi-Interface (MI) Shoe™, 32bit float⁴ audio travels digitally and directly to a compatible camera and records with video in a single file¹. Up to 64 GB⁵ of built-in memory enables 32bit float backup audio recording directly on the transmitter. Integration with compatible Sony wireless headphones enables cable-free monitoring and microphone functions². Power supply and linked power control through the MI Shoe on compatible cameras support an efficient workflow from recording through editing. The supplied USB Type-C^® adapter also enables connection to compatible smartphones and PCs⁶. The transmitters and receiver are also sold separately, supporting configurations such as up to four-channel recording and multi-camera production.

"Video creators are working in increasingly dynamic environments, often with smaller teams and less room for error," said Yang Cheng, Senior Vice President of Imaging Solutions, Sony Electronics. "With the ECM-W5, we focused on the real workflow challenges creators face: moving freely, managing multiple voices, staying in sync, and protecting every take, so they can spend more time focused on the story and less time managing audio."

Availability and Price

Pre-orders for the ECM-W5 begin 7 AM PT/10 AM ET, October 14, 2026.

Key Features of the ECM-W5

High-quality recording that captures subtle nuances in sound

The high-performance microphones support 96 kHz High-Resolution Audio recording¹, capturing voices with clarity and detail. A 3.5 mm microphone input also supports lavalier and external microphones, including the separately sold ECM-L1, providing flexibility for different recording situations.

Stable audio transmission and recording functions that support an efficient workflow

The system supports line-of-sight transmission at distances of up to 500 m³. It provides approximately three times more stable transmission than the ECM-W3⁷. In congested radio-frequency environments, it is designed to reduce audio dropouts and hold a reliable connection. Low-latency transmission supports applications where real-time audio performance is important, including live streaming.

32bit float⁴ recording helps creators capture both quiet and loud sounds without the need for constant gain adjustment and suppresses the possibility of clipping⁸. Through the MI Shoe, 32bit float audio travels digitally and directly to a compatible camera and records with video in a single file¹, with no external recorder and no separate audio file to manage, eliminating the work of synchronizing audio afterward.

The transmitters carry 64 GB⁵ of built-in storage for backup. The storage holds up to 90 hours of audio at 32bit float/48 kHz or up to 60 hours at 24bit/96 kHz¹, retaining the source recording.

New audio recording styles through integration with Sony wireless headphones

Compatible Sony wireless headphones² enable cable-free monitoring, giving creators greater freedom to move while checking sound during recording. Compatible models² can also be used as wireless microphone inputs.

Versatile functions for comfortable shooting and recording

The system records up to four channels of audio in-camera, covering interviews, panel discussions, event production, and other multi-source needs. The supplied wireless transmitters combine with the separately sold ECM-W5T wireless transmitter, and the system also works with external microphones.

Timecode functionality helps simplify synchronization across multiple cameras and audio recordings, helping reduce manual alignment work in post-production.

Through the MI Shoe, compatible Sony cameras can provide power to the receiver and support linked power control. The supplied USB Type-C^® adapter enables recording on compatible smartphones and PCs⁶, and connecting a transmitter directly over Bluetooth^® allows wireless recording⁹. The transmitters provide up to 11 hours of operating time. A dust- and moisture-resistant design supports use in a range of environments¹⁰.
