BOYA BY-MM1 Microphone - Compact, Cardioid, No Batteries - Video Recording

BOYA BY-MM1 Microphone - Compact, Cardioid, No Batteries - Video Recording arrives as a compact on-camera solution designed for creators who need clear audio without fuss.

The BOYA BY-MM1 is a compact cardioid microphone with a 3.5 mm (1/8") wired connection, making it easy to plug directly into cameras, recorders, or smartphones (with adapters). Its plug-and-play design requires no batteries, so you can focus on shooting rather than powering the mic.

Built to capture focused sound, the cardioid pickup pattern reduces background noise and emphasizes the subject in front of the camera. With a sensitivity of -42 dB and a frequency response from 35 to 18,000 Hz, the BY-MM1 provides clear voice and ambient capture suitable for video production, vlogging, interviews, and field recording.

Despite its small footprint—81 mm wide with a 2.2 cm diameter and weighing only 86 g—the microphone offers a strong signal-to-noise ratio of 76 dB, delivering clean, professional-sounding results. The wired connectivity and standard 3.5 mm interface keep setup simple and compatible with many devices.

The BY-MM1’s durable black housing and compact form factor make it an unobtrusive addition to your camera rig. The package includes one microphone, ideal for solo creators or as an onboard mic for DSLR and mirrorless cameras.

Use cases include run-and-gun vlogging, on-location interviews, social media content creation, and quick product or how-to videos where mobility and simplicity matter. It’s also a reliable choice for live-streaming when paired with a camera that accepts a 3.5 mm input.

Key selling points are its battery-free operation, cardioid pickup for focused audio, broad 35–18,000 Hz frequency range, and high 76 dB SNR for low-noise recordings. The BOYA BY-MM1 combines portability and performance for creators at any level.
