The MightyMic SLR from AmpRidge is a compact condenser shotgun microphone that does not need any batteries. It can be used to capture audio in applications for DSLRs, camcorders, iPhones, iPads, iPod touch, Samsung Galaxy devices, and more.
The MightyMic SLR Shotgun mic comes with several features. It is built with a 4-pin TRRS 3.5mm mini-jack connector and plugs directly into the headphone jack of your smart-device. In the same way, the included coiled cable allows you to convert the 4-pin microphone connector to a 3-pin 3.5mm mini-jack connector that is used for DSLR cameras.
The microphone needs no batteries because it is powered by the device. It is designed to reject sounds from the back and sides, minimizing unwanted sounds, yet is small enough to not get in your shot when using a wide-angle lens. You can use the optional MoviePro App (iOS only and sold separately at Apple App Store) to listen to the audio while recording video and then adjust the volume accordingly. In addition, the microphone comes with a foam windscreen, a carrying pouch, an adapter cable, and a cold shoe clip.
