Equipped with a USB Type-C connector, just plug it into a compatible Android device, and you can use it as an external stereo microphone with high sound quality. Mid-Side stereo microphone combines a unidirectional Mid microphone and a bi-directional side microphone. You can freely control the stereo image spread (stereo width) by changing the volume of the side microphone. The stereo width adjustment switch allows you to switch between 3 types, including the standard 90°, a wider 120°, and the M-S that can be adjusted from later. You can make stereo recording sound according to your needs. The unique microphone rotation mechanism also keeps the correct stereo position even when shooting horizontally with your smartphone. With the free "Handy Recorder" app available from Google Play, you can record high quality linear PCM recording, edit audio, processing effects and share recorded files.
