Equipped with the Comica Audio CVM-VM20 camera-mount shotgun microphone, any run-and-gun videographer, mobile journalist, or vlogger can shoot on a camera or mobile device and capture markedly improved sound quality. The mic's auto-configuring 3.5mm TRRS output allows you to use the included TRS to TRRS cable whether you shoot with a smartphone, tablet, DSLR, or camcorder. And forget about stocking spare batteries; the CVM-VM20 can run off its internal rechargeable battery or a USB power source.
Thanks to the stepless gain dial, the CVM-VM20 offers convenient optimization of your recording level at the mic, so you don't have to crank up the gain (and subsequent noise) on your recording device. If you encounter bass buildup from rumble, engage the onboard low-cut filter to 75 or 150 Hz according to the situation. The included shockmount reduces camera handling noise, further contributing to clean, intelligible recordings.

The CVM-VM20 features a 3.5mm TRRS output with automatic TRS/TRRS sensing functionality, making it compatible with most 3.5mm microphone input jacks. Whether you shoot with a smartphone, tablet, DSLR, or camcorder, the CVM-VM20 makes it easier to get setup and start recording. The mic is supplied with a 3.5mm TRS to TRRS cable, so you don't have to change to a different cable just to switch from your smartphone to a camera.
By incorporating a stepless gain dial with up to 20 dB of boost, the CVM-VM20 lets you easily optimize your recording level without relying on the often-noisy gain stage built into cameras and mobile devices.
With the CVM-VM20's low-cut filter, selectable at 75 or 150 Hz, you can attenuate low-frequency rumble at the mic rather than having to address the issue in postproduction.
Whereas most mics built into cameras and mobile devices capture sound from all directions, the condenser capsule of the CVM-VM20 utilizes a supercardioid polar pattern to deliver narrow frontal pickup and effective rejection of sound at the sides. This gives you more intelligible speech and sound effects recording with less overall ambience.
Equipped with an internal 320mAh lithium-ion battery, the CVM-VM20 keeps you rolling for hours and hours. When it's time to recharge, just use the supplied USB Type-C cable to connect the mic to a computer's USB port, a USB power supply, or a USB battery pack. The CVM-VM20 can be operated while its battery charges, allowing extended run time for long shoots.
The onboard OLED screen serves as a real-time power monitor, showing a highly visible meter for the battery. Use the power switch to turn off the mic during periods of inactivity to reduce battery drain.
Thanks to its metal construction, the microphone is not only tough, but also shielded against radio-frequency interference.
The included shockmount attaches to a camera shoe mount and decouples the mic from your camera, minimizing the transfer of vibrations from camera handling noise. Slip the supplied foam windscreen to reduce noise from light wind and fans. For enhanced protection against wind noise in outdoor shoots, use a furry windshield (available separately). The CVM-VM20 comes with a case to enable safe and convenient transport of the mic from gig to gig.
