Boya BY-MM1 Compact Cardioid Microphone

4 reviews

Precision audio in a small package

Cardioid microphones mitigate sounds from the sides and rear, allowing you to get a cleaner signal from your subject.  This often makes a cardioid mic the ideal choice for on camera use.  Super-cardioid mics like the BY-BM3031 have superior side and rear rejection, but the BY-MM1 strikes a nice balance in a small form factor.

Plug and Play

The BY-MM1 requires no battery, and works on most cameras, camcorders, and smartphones, and computers.

Rugged Construction, Compact Design

The BY-MM1 is tiny, and makes a night and day difference to your audio when compared to any built-in mic.  Its sturdy metal body will help it survive everyday use for years to come.  Having this mic in your bag is a no-brainer!

Anti-shock mount and wind sock included

The BY-MM1 comes fully loaded with the extras you'll need to mitigate sounds transferred through your camera body, as well as unwanted wind noise.

    Great for the price!

    I’m not a super tech savvy type of person but this little mic is so beginner friendly and performs well to have a little something more than your phone’s mic. Super affordable compared to other brands too!

    Pretty good value

    Sound is pretty decent for the price, and it seems to work fairly well. Easy to use, jusy plug it in and it works. Only problem is occasional balancing issues when trying to stand it up on my desk.
