On-Camera Shotgun Microphone

The BOYA BY-BM3031 is a supercardioid condenser shotgun microphone built for on-camera use with DSLRs, camcorders and audio recorders. It mounts via an integrated cold shoe and connects through a 3.5 mm mini-jack output. The design targets creators who need clearer dialogue capture than built-in microphones provide.

Low-Cut Filter and Gain Switch

A switchable high-pass filter at 80 Hz rolls off low-frequency rumble while a three-level gain control offers -10 dB pad, 0 dB unity and +20 dB boost settings. This combination replaces the fixed gain and absent filtering found on many camera inputs, making the jump worthwhile when recording environments produce wind, handling noise or sudden volume spikes.

For Solo Video Creators

The unit suits vloggers, interviewers and run-and-gun videographers who need a lightweight, battery-free microphone that mounts directly on a cold shoe. Buyers who require XLR connectivity, phantom power or stereo capture should look at alternative solutions.

Questions about this item

What size microphone jack does the BY-BM3031 plug into?

The microphone uses a 3.5 mm output mini-jack connector for cameras, camcorders and audio recorders.

How do I mount the BY-BM3031 and which step is often missed?

Slide the cold shoe foot onto the camera hot shoe and tighten the locking wheel; many users forget to lock the wheel, so the mic can twist loose.

When should I replace the foam windscreen on the BY-BM3031?

Replace it when the foam starts to crumble, stays compressed or no longer fits snugly over the capsule, usually after extended outdoor use.
