Product Information
The Sony ECM-W5 Wireless Microphone Kit is an all-in-one wireless audio system for compatible Sony cameras, smartphones, and computers. Two included microphone/transmitters, a receiver, and a charging case support flexible two-person capture, while up to four in-camera channels are available when optional ECM-W5T transmitters are added.
Audio built for the edit
Record up to 96 kHz/24-bit audio or use 48 kHz/32-bit float recording to preserve quiet voices and sudden peaks with greater flexibility in post. With a compatible Sony camera, 32-bit float audio can be recorded in the video file to keep audio and picture together in one workflow. Each microphone also has 64 GB of built-in storage for onboard recording and backup options.
Wireless production tools
The ECM-W5 offers stable, low-latency wireless transmission at distances up to 500 m in line-of-sight conditions. A Bluetooth LE Audio connection supports cable-free monitoring with compatible Sony wireless headphones, while timecode synchronization can help align footage in post-production. Each transmitter and the receiver also provide a 3.5 mm external microphone input for a compatible lavalier microphone.
