The Boya BY-MM1 is a cardioid microphone, specifically designed to improve the audio quality of video recordings compared to the recording device's internal microphone. Included in the package are two cables (TRS and TRRS), which allow the microphone to be used with the vast majority of devices, such as cameras, smartphones, camcorders, audio recorders, computers, and other audio/video recording devices.
The microphone's structure is made of aluminum, keeping it compact, lightweight for transport, and durable over time. Thanks to its plug-and-play design, it can be mounted and used directly on devices, without any modifications needed and, most importantly, without requiring batteries.
An anti-shock mount is included to significantly reduce accidental vibrations and noises caused by the cable and mounting. Furthermore, a wind muff is included in the package, very useful for minimizing wind noise and environmental factors during outdoor shooting.
