The microphone features a shoe mount adapter with locking screw to attach directly to a camera's hot shoe or to any cold shoe mount. A 3.5mm jack with a coiled cable plugs into a compatible camera and a foam windscreen is included to reduce unwanted sounds. Also included is the MicPro adapter which enables the Boomer to connect to an iPhone's headphone jack for audio recording. The Boomer microphone requires one AAA battery as its power source.
