Whether you shoot with a mobile device or a camera, the BOYA BY-MM1 PRO ultracompact camera-mount shotgun microphone offers the flexibility of selectable sound pickup orientation as well as improved audio quality over the mic built into your device. The BY-MM1 PRO utilizes two supercardioid capsules (one at each end) and a 3-position switch to enable selectable directionality from the front, the rear, or both ends.
