Clear audio pickup from any direction

The ECM-W2BT can be positioned close to the speaker's mouth with a clip. The omnidirectional mic capsule also helps to pick up your voice clearly wherever it's coming from, so there's no need to worry about which way the unit is facing.

Effective noise suppression during audio transmission

Unlike conventional analogue audio transmission, you'll never need to worry about cable signal interference. Just pair the ECM-W2BT with the compatible Sony camera with a Digital Audio Interface via a Multi Interface (MI) Shoe for clear, low-noise, all-digital audio.

Simple audio optimisation for any source

An attenuator function lets you easily adjust recording levels appropriately to match the source. Simply flip a switch to reduce the level of very loud sounds or amplify quiet ones, for optimised audio levels.

Clear sound even outdoors in the wind

The unit comes with a wind screen, allowing comfortable recording when shooting outside. Just attach the wind screen to the mic, and it effectively reduces wind noise as well as breath noise, for clear and stable sound even when shooting outdoors on a windy day.

Stable transmission between microphone and receiver

Qualcomm® aptX™ Low Latency¹ Bluetooth® codec is used for transmission between the microphone and receiver units, ensuring low latency and undiminished audio quality. It helps avoid the stress of having to re-record audio due to interruptions in the recorded sound, and low latency enables better matching of the audio track with the video imagery.
