Sony has introduced the ECM-W5 wireless microphone system, pairing two transmitters with a receiver for direct 32bit float recording to compatible cameras. Scheduled for November 2026 availability, the kit carries an MSRP of US $399.99 or CA $569.99, and Sony opened preorders on October 14. Through a compatible camera’s Multi-Interface (MI) Shoe, the system can store digital audio alongside video within one file, removing a separate synchronization step during editing.
The system also supports 96 kHz High-Resolution Audio capture, but 32bit float recording works only at 48 kHz. Sony says 32bit float reduces the need to keep adjusting gain for changes in volume and helps prevent clipping. That protection has a limit: audio that clips at the microphone input cannot be recovered through volume changes in editing.
Each transmitter includes 64 GB of storage for backup recordings, with formatted capacity below that figure. Sony rates recording capacity at up to 90 hours using 32bit float at 48 kHz, or up to 60 hours using 24bit at 96 kHz. The transmitters have a stated operating time of up to 11 hours.
Sony rates wireless reach at up to 500 m with an unobstructed view between microphone and receiver, although obstacles and radio conditions affect that distance. The company claims transmission is approximately three times as stable as the ECM-W3 under its internal measurement conditions. Compatible Sony wireless headphones can serve both as monitoring devices and microphone inputs.
For larger setups, the ECM-W5 supports in-camera capture of up to four audio channels, while timecode helps align recordings across cameras and audio devices. Separately, the ECM-W5T transmitter costs US $119.99 or CA $169.99, and the ECM-W5R receiver costs US $189.99 or CA $269.99; both are scheduled for November. A supplied USB Type-C adapter connects the system to compatible phones and PCs supporting USB Audio Class 2.0, while a 3.5 mm input accommodates external microphones.
Sony also recently opened preorders for the ECM-AX10, a US $249.99 smartphone microphone that uses four omnidirectional capsules to record spatial audio. That model connects directly to compatible USB-C phones and requires Sony’s dedicated app for video capture, editing and export.
