Sony has unveiled its new ECM-W5 wireless microphone system, taking aim at the increasingly competitive market dominated by the likes of the DJI Mic 3 and RØDE Wireless PRO. However, rather than simply matching its rivals on specifications, Sony is leaning heavily into its camera ecosystem to offer something a little different.
The biggest selling point is the ability to record 32-bit float audio wirelessly, directly into a compatible Sony camera's video files through its Multi Interface Shoe, eliminating the need to synchronize separate recordings afterward.
The DJI Mic 3 also supports 32-bit float recording and can connect digitally through Sony's hot shoe using an optional adapter, but this connection is limited to 24-bit audio, with 32-bit float recordings stored separately on the transmitters.
Sony's transmitters also offer 64GB of internal storage compared with the DJI's 32GB, providing up to 90 hours of backup recording. Its claimed 500-meter wireless range also beats the DJI Mic 3's 400 meters, although both figures represent ideal line-of-sight conditions rather than guaranteed real-world performance.
Elsewhere, the ECM-W5 supports four-channel recording, timecode synchronization, and 96kHz high-resolution audio, although the latter is limited to 24-bit recording. Four-channel recording also requires purchasing additional transmitters, rather than being available with the two included in the kit.
One of Sony's more interesting additions is Bluetooth headphone integration, allowing creators to monitor audio wirelessly using compatible Sony Bluetooth LE Audio headphones, rather than being tethered to the camera. Better still, select Sony headphones and earbuds can actually double as microphones, sending audio directly to the receiver without needing a dedicated transmitter. Sony is even promising binaural recording through its WF-1000XM6 earbuds via a future firmware update.
There are 3.5mm microphone inputs on both the transmitters and receiver, dust- and moisture-resistant construction, and power supplied directly from compatible Sony cameras through the Multi Interface Shoe.
Battery life is a slightly less impressive area, with Sony quoting seven hours of continuous use per transmitter, extended to 11 hours with the charging case when the receiver is powered by the camera. DJI, meanwhile, promises eight hours from its transmitters and up to 28 hours with its charging case.
For Sony camera owners, the appeal is clear: professional audio with fewer cables and less post-production work. However, for creators regularly switching between different camera brands, DJI and RØDE offer broad compatibility and similar features, and Sony's added convenience comes at a premium.
The ECM-W5 costs $399.99 / £350, compared with the DJI Mic 3's $259 / £215 for an equivalent two-transmitter kit. Sony's ECM-W5 will be available from November 2026, with standalone receivers priced at $189.99 / £180 and transmitters at $119.99 / £110.
