The Ampridge MightyMic S. It’s the shotgun mic for your iPhone! I got this one via Photojojo. I did a quick test and it sounds good. I’m going on the road with it this week to put it through more of a workout.
The MightyMic S microphone brings big sound from a small microphone. Don’t be fooled by the compact size. This is a high quality condenser microphone that does not need any batteries as it is powered by the device. So you never get stuck doing that big video shoot only to find out the batteries are dead. Just plug it into the headphone jack of your device. Then connect your headphones into the 3.5mm stereo headphone jack on the back of the microphone. While using the optional MoviePro app you can listen to the sound while recording video and adjust the volume. For audio recording just open the GarageBand app and select the microphone input. It works with iPhone, iPad, and iPod Touch and other devices.
The mic comes with a foam windscreen and handy little zip pouch to keep it in. I have become used to using the Zoom Handy Recorder app to record with on my iPhone 5 S and it works fine with this little Mighty Mic S. Now I have multiple mic options for my iPhone which I have been using more and more for interviews on the agriblogging highway.
