The Sony ECM-AW3 makes it easy to get clear, professional-quality audio recordings of your subjects without worrying about wires. This compact microphone uses Bluetooth® technology to wirelessly transmit sound up to 150 feet from your subject to the matching receiver, which plugs into your compatible camcorder. This combo lets you capture a lifelike recording of your daughter's impromptu concert in the living room, or create a high-quality copy of a conference or lecture.

The receiver connects to select Sony camcorders via the microphone input. An armband is included so you can wear the receiver on your arm — within easy reach but out of your way. The ECM-AW3 also comes with two earphones, one for the mic and one for the receiver, which enables two-way communication between you and your subject. This unique feature allows you to give your subject direction while capturing only their voice.

Crutchfield Customer Review (What's this?)

This microphone for my Sony camera I couldn't be more pleased. It performs like I hoped it would. The clarity is unbelievable. I can record voice clearly with no problem the length of an olympic sized ice arena. I would recommend this product to anyone. Cost and delivery were fantatsic. Get yours today!!

Pros: Easy operation. Easy to hook up and break down.

Cons: Battery life. But I wouldn't let that deter you. Roughly 4 hours of continuous life.

Product Research


Overview: The Sony Bluetooth Wireless Microphone (ECM-AW3) allows you to capture crisp, clear audio from up to 150-feet away from your camcorder that features a 3.5mm microphone input. The ECM-AW3 includes a wireless microphone and wireless receiver, and comes supplied with an armband, wind screen, carrying pouch, and two mono-earphones.

Compatibility: The Sony Bluetooth Wireless Microphone is compatible with almost any recording device such as video camera or recorder with a 3.5mm microphone input jack. The included wireless receiver connects to your camcorder's 3.5mm microphone input, using the supplied minijack cable.

Microphone Type: The Sony ECM-AW3 utilizes a monaural, non-direction, electoret condenser microphone with a frequency response of 300 to 9,000 Hz.

2-Way Communication: The Sony ECM-AW3 allows two-way communications between you and your subject, enabling you to give your subject direction while capturing only their voice. Even when far away (up to 150 feet) from the camcorder, you can also shoot while recording whole conversations between you and your subject.

Separate Earphones: Two separate mono-earphones are provided for both the microphone and the receiver units. An earphone hanger is supplied if the earphone comes out too easily when used by a child or someone with small ears.

Mounting: The wireless microphone and wireless receiver each have a spring-clip allowing you to attach them to your clothing. Also, included is an hook & loop armband.

Wind-Screen: The wireless microphone comes with a wind-screen to cut down on wind noise during your audio/video recording.

Battery Powered: The wireless microphone and wireless receiver each operate off of a single "AAA" alkaline or rechargeable Ni-MH battery. A single "AAA" battery provided a continuous operating time of approximately 3 hour and a standby time off  approximately 9 hours (for microphone) and 3 hours (for receiver).

Carry Pouch: The Sony ECM-AW3 comes supplied with a draw-string cloth carrying pouch for easy storage and portability.
