San Diego – October 14, 2026 -- Sony Electronics has introduced the ECM-W5 wireless microphone system for video creators, and pre-orders open at 7 AM PT/10 AM ET on October 14, 2026. The system pairs two transmitters with one receiver and sends audio over a line-of-sight distance of up to 500 m.
32bit float audio lands in a single video file
Through the Multi-Interface (MI) Shoe, 32bit float audio travels digitally and directly to a compatible camera and records with the video in a single file. There is no external recorder and no separate audio file to sync later. The 32bit float mode works only at 48 kHz. It is meant to capture quiet and loud sounds without constant gain adjustment and to reduce the chance of clipping.
The microphones also support 96 kHz High-Resolution Audio recording, and a 3.5 mm input accepts lavalier and external microphones, including the separately sold ECM-L1.
Transmitters keep a 64 GB backup of every take
Each transmitter carries 64 GB of built-in storage for backup recording. That holds up to 90 hours of audio at 32bit float/48 kHz or up to 60 hours at 24bit/96 kHz. Sony says the transmission is approximately three times more stable than the ECM-W3, based on its internal measurements, and is designed to reduce dropouts in congested radio-frequency environments. Low-latency transmission is aimed at uses such as live streaming.
Sony wireless headphones become monitors and microphones
Compatible Sony wireless headphones allow cable-free monitoring while recording, and compatible models can also serve as wireless microphone inputs.
Four channels, timecode and phone or PC recording
The system records up to four channels of audio in-camera, aimed at interviews, panel discussions and event production. Adding the separately sold ECM-W5T transmitter expands the setup, and timecode functionality helps synchronize multiple cameras and audio recordings.
Compatible Sony cameras can power the receiver and provide linked power control through the MI Shoe. A supplied USB Type-C adapter enables recording on compatible smartphones and PCs that support USB Audio Class 2.0. A transmitter can also connect directly over Bluetooth for wireless recording. Transmitters run for up to 11 hours, and the design is dust- and moisture-resistant, though not guaranteed to be 100% proof.
Yang Cheng, Senior Vice President of Imaging Solutions at Sony Electronics, said the ECM-W5 targets creators who work in dynamic environments with smaller teams and less room for error.
