The Sony ECM-W2BT brings vloggers, YouTubers, journalists, and content creators using Sony cameras with digital MI interfaces a flexible and easy-to-use true-wireless microphone system featuring advanced Bluetooth technology for high-quality audio and reliable, low-latency performance.

The miniature clip-on transmitter with a built-in omnidirectional microphone makes it fast and easy to mic up your subject for a quick interview without having to worry about a cable. The transmitter also features a stereo 3.5mm audio input, allowing you to connect a smaller, more discreet lavalier such as the ECM-LV1 (available separately) if desired. 

The compact receiver attaches directly to the MI shoe mount on compatible Sony cameras, giving the system up to 9 hours of shooting time, assisted by the camera's power. Both the transmitter and receiver are powered via built-in rechargeable lithium-ion batteries; without an MI connection, the system will operate for up to 3 hours between charges. If the camera's MI shoe is also equipped with a digital interface, the direct connection allows the camera to record pristine sound with an ultra-low noise floor.

A smart feature is an addition of a built-in microphone on the receiver unit, along with a 3-setting switch allowing you to pick up audio from either the subject at the transmitter, the camera operator at the receiver or both at the same time for interviews. The receiver also features a 3.5mm output for connection to traditional DSLR/mirrorless cameras and a 3.5mm TRS cable is supplied along with a USB cable and a windscreen for the transmitter/mic.

Fast and Easy Wireless Audio with High-Quality Advanced Bluetooth

• The small, clip-on transmitter features an internal microphone capsule that picks up sounds cleanly and clearly to deliver a high-quality audio stream. The microphone is also effective at suppressing extraneous noise.
• The omnidirectional microphone picks up sound from all directions. Use the clip to place the microphone near the speaker's mouth, without worrying about which direction it's facing. 
• The Qualcomm aptX Low-Latency Bluetooth codec is used for transmission between the microphone and receiver on the camera, ensuring low latency and undiminished audio quality. The system's reliability helps you avoid the stress of having to re-record audio due to interruptions in the recorded sound, and low latency enables you to better match the audio track with the video imagery.

Cable-Free MI Digital Connection to Select Sony Cameras

• With the convenient power interface provided by Sony cameras with an MI shoe, you can record wirelessly for up to nine hours.
• You can also benefit from improved sound quality through the use of the MI Digital Audio Interface (available on compatible cameras), ensuring pristine digital sound quality.
• Both the transmitter and receiver feature built-in rechargeable batteries.
• The battery life of the receiver will be up to three hours of use when paired with cameras that do not support the power supply via the Multi Interface Shoe.
