Audio is the thing that can Make or Break a video. There are times when a Wireless Microphone is needed. Maybe a Speech needs to be filmed. Or, a video where the talent or actor moves around on camera and can’t be tied to a Wired microphone.
Well, a great option is the Sony ECM-AW4 Wireless Bluetooth Lavalier (Lapel) Microphone!
It’s a Great Value for what it does. It is a Transmitter/Receiver pair, much like higher priced wireless option, only it uses Bluetooth Technology instead of Radio Frequency. The Transmitter and Receiver each use a single AAA battery for power. The receiver gets plugged into either a Smartphone or a camera. The Microphone (transmitter) gets clipped to your shirt/lapel.
Pricing for this Sony ECM-AW4 Bluetooth Microphone is from $150 to around $200 (sometimes higher) as of this writing. It is available from multiple sellers on the internet or some Big Box stores.
In the video below, I shot good sound at approximately 125 feet away, through a closed window!! I had the transmitter clipped to the front of my shirt and the receiver was plugged into an iPhone 4s back in my house as I shot the video through a window!! The iPhone 4s captured the Audio ( and some of the video) from the whole video shoot.
