Microphone BOYA BY-MM1

The BOYA BY-MM1 is a compact cardioid microphone designed to improve the sound quality of videos recorded with built-in microphones. It provides wired 3.5 mm connectivity and includes both TRS and TRRS cables for use with cameras, camcorders, smartphones, audio recorders, and PCs. The microphone has a sensitivity of -42 dB, a frequency response of 35–18,000 Hz and a signal-to-noise ratio of 76 dB, all in a lightweight aluminum housing weighing 86 g.

Advantages

The cardioid polar pattern reduces off-axis noise and focuses on the subject, delivering clearer vocals and on-camera sound. The plug-and-play wired design requires no battery, enabling reliable operation without power management. The package includes an anti-shock mount that reduces handling and cable noise, and the compact, lightweight metal construction is convenient for handheld and on-camera use.

Suitable for

• Vlogging and on-camera video recording
• Interviews and field recording with cameras or smartphones
• Podcasting and voiceovers with recorders or PCs
• Streaming and content creation requiring improved built-in mic quality

How to use

Use the included anti-shock mount to minimise handling noise during recording.

Recommendations

For best results, position the BOYA BY-MM1 within 30–60 cm of the speaker and point the microphone directly at the sound source. When using smartphones, set the device to external microphone input if required by the app. Avoid strong wind or use a windscreen for outdoor recording to reduce wind noise.
