Record improved audio with your DSLR/mirrorless camera, compatible mobile device, or audio recorder using the BOYA BY-BM2040 Camera-Mount Shotgun Microphone. Its supercardioid pickup pattern focuses on subjects in front of the microphone and reduces surrounding noises. A 3.5mm TRS output port on the microphone can be plugged into your compatible device of choice using the included 3.5mm TRS or TRRS cables.
