The Boya BY-MM1 is a shotgun directional microphone that lets you improve the audio recordings of videos. You can connect the microphone to a camera or smartphone via the included TRS cable with 3.5mm jack. Thanks to its compact size and lightweight aluminum construction, the microphone is easy to transport. The included anti-shock mount reduces vibrations and accompanying noise pollution. You can also use the microphone outdoors, thanks to the included windscreen, which reduces white noise and wind sounds.
