Improve Your Production Versatility

Improve the production quality of your vlogs, podcasts, interviews and presentations with the Sony Bluetooth Microphone ECM-AW4. With its simple 3.5mm mini-jack input and the ability to support an external microphone, it’s the perfect solution for a wide range of audio and multi-media applications.

45m Line-Of-Sight Range

Consisting of a separate transmitter and Bluetooth microphone, the system combines to deliver wireless audio pickup as far as 45m line-of-sight. This amazing range means you're untethered from the camera, opening the door to a new world of creative possibilities for documentaries, short films, interviews, electronic news gathering and more.

3.5mm Headphone Jack

A 3.5mm headphone jack on the receiver allows audio monitoring, taking the guesswork out of adjusting audio levels and ensuring the presenter has nailed their lines if they are being filmed from a distance.

2-Way Talk-Back Function

Its bluetooth technology adds another impressive feature that allows a camera operator or scene director to speak with the subject to provide feedback on the scene or suggestions for the next take. Streamlining the creative process, the talk-back function utilises the 3.5mm headphone jack on the transmitter to enable convenient, real-time advice, or to discreetly feed lines to the presenter when shooting from a distance.

3.5mm Mini-Jack Input

Compatible with virtually any digital camera, camcorder, audio recorder or other device that features a 3.5mm mini-jack microphone input means the ECM-AW4 can be used for things beyond recording vlogs and interviews.

External Mic Compatible

The 3.5mm output on the transmitter is plugin power compatible enabling you to add more specialised external microphones - such as a lapel mic, to better suit your individual recording scenario.

Includes Arm Strap

A simple spring-loaded clip at the rear of both the transmitter and receiver provides a broad range of discreet mounting possibilities. Attach it to a shirt pocket, a hip belt, a camera strap or the included arm strap for comfortable, accessible mounting.

Easy-Swap Battery Power

Powered simply by 1 AAA in the receiver and transmitter facilitates the ability for you to quickly swap out batteries on the Sony Bluetooth Microphone (ECM-AW4) and keep shooting. No waiting to recharge an internal battery necessary!
