Designed to enhance the sound quality of vlogs, YouTube shorts, Facebook clips, and other video content produced with DSLR/mirrorless cameras, smartphones, and other devices with a 3.5mm input jack, the BOYA BY-BM2021 Camera-Mount Shotgun Microphone is a small, lightweight microphone. The BY-BM2021 has a true plug-and-play design that requires no battery and mounts straight to the shoe mount on your camera. By concentrating audio capture directly in front of the microphone, the supercardioid polar pattern reduces background noise and other ambient sounds. The microphone has a shockmount to absorb vibrations that cause noise and is constructed of ABS plastic. The foam windscreen that comes with it helps to cut down on wind noise. In addition, there is a 3.5mm TRS to 3.5mm TRS cable for cameras, audio recorders, and camcorders.
