Reliable Audio Transmission
Audio can be transmitted from up to 656' away thanks to its 2.4 GHz auto frequency hopping technology and upgraded Bat Obstacle Avoidance 2.0 technology to prevent cut-offs or interference. Three different volume settings can be toggled depending on your recording setting. Use "High" when recording from a long distance, "Medium" when interviewing in an open space, or "Low" for recording in a small office or closed studio. Built-in device identification auto-adjusts the volume setting on your connected mobile phone or camera.

Smart Noise Cancellation
HearClear smart noise cancellation can be turned on with the touch of a button to filter out unwanted noise and maintain vocal clarity. Loud ambient noise like traffic or crowds are eliminated in instances like outdoor interviews. If you want to maintain room tone, simply turn noise cancellation back off.

Easy-to-Configure
Clips on the back of both transmitters allow you to attach them to your subject's lapel, and their lightweight design ensures it does not tug on the fabric. Two included windscreens can be attached to the transmitters to mitigate interference from the wind. Intuitive plug-and-play pairing allows you to use the system right out of the box.
