This compact and lightweight mic might be exactly what you have been looking for. We took a look at the Comica  CVM-VM20  to find out just how well it works from the perspective of a videographer. It is a budget miniature shotgun with a 3.5mm TRRS output. This device is designed with a smart 3.5mm interface, universal for mobile phones and cameras.  The Comica VM20 includes many features, such as a metal body, smooth volume control, and a rechargeable battery.  We will be comparing the Comica CVM-VM20 Microphone to the Rode VideoMic NTG in terms of compatibility and functionality.

How it works

The Comica can be compared to the RODE VideoMic NTG both visually and in functionality. Although both microphones are versatile, we think that the Comica might come out on top. In the last few years, we have seen manufacturers start to make products that are multi versatile and can be used for a wide range of applications. The Comica has a complete universal capability so that you can connect to all of your devices. It uses a super-cardioid polar pattern and variable to gain control, which allows the user to precisely adjust the mic’s output. The Rode VideoMic NTG lets you output an audio signal through the USB-C, making it easy to use as a microphone for your computer. You can also use the headphone output for audio monitoring while using the USB output. Neither of these things is possible to do with the Comica. However, The Comica is made out of a metal material that can shield external signal interference, stable and durable. The microphone can deliver anything from a mic level signal all the way to a headphone level output.

Filter Modes

The CVM-VM20 has two low-cut filter modes, 75 & 150Hz. These two low-cut filter modes can effectively filter out the low-frequency noise according to different operating conditions. There is a simple button on the microphone that you press to activate these low-cut filters. The blue LED indicates which option has been selected. If it is turned off, then the no low-cut filter has been selected. However, the Comica CVM-VM20 has the same pick-up pattern as the Rode VideoMic NTG.


The microphone has an In-built rechargeable lithium-ion battery. This battery lasts up to 60 hours of recording. The USB-C interface design supports charging while using to extend the microphone’s working time. By having a rechargeable battery built-in, you do not have to remove anything. We all know that replacing the 9V on the Rode is a huge pain in the butt. Depending on how often you are recording, this battery should last you days, if not all week. The LCD screen for battery display and real-time power monitor ensures that your recording goes smoothly.

Compact & Lightweight

The Comica CVM-Vm20 Microphone weighs 91 grams but also comes with its own carrying case for safe storage. Its small size makes it easy to travel with (22mm x L 177mm), making it fit into pretty much any bag. However, it is longer than the RODE VideoMic NTG. While the RODE VideoMic NTG weighs 94g.

Volume Control

With the incorporated step-less 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. The adjustable step-less gain control lets you change the output level of the microphone. This goes from 0-10. The trouble is, unlike the version on the RODE VideoMic NTG, where the level you select is always shown on the top of the microphone, on the Comica, you can only see when 3-6 is selected. With any other values you set, the red indicator can’t be seen.

Additional Feature

The value for the price is unbeatable. Not only does the microphone hold significant-quality, but it also comes with accessories. The Comica comes with a Shock Mount that allows you to adjust the microphone's angle with a standard twist to tighten the mechanism. The 3.5mm TRS-TRS audio cable and USB-C to a USB charging cable are also included. The carry case is also in the box with the user manual. It also winds Jammer and thick wind muff for wind protection. This certainly makes a difference when you are using the microphone outdoors. The Rode VideoMic NTG doesn’t come with a windjammer like this as standard. Bottom Line  Considering the price, we thought the Comica sounded pretty impressive. Now that we have compared both microphones, it seems like an unfair test as the Rode costs almost twice as much as the Comica. Nonetheless, we hope this article gives you an idea of the quality and functionality of both microphones. There are also many different microphones and accessories available here. Now we want to hear what you think. Have you ever tried out the Comica or Rode VideoMic NTG? How did it work out for you?
