Comica CVM-WM100PLUS - Wireless Microphone System for Cameras, Camcorders, Smartphones, Laptops, Professional UHF Wireless Lavalier Lapel Microphone with Dual-Channel Recording, AA Batteries

I've been in Pro Audio for more than 40 years, having used wireless from all of the major pro brands, so my expectations were pretty low. I needed a wireless lavalier setup for some corporate videos we're shooting, so rolled the dice knowing I could send it back to Amazon. I also bought an 8-pack of Amazon Essentials 2400mA rechargeable batteries for the 6 needed plus two spares.First, the value proposition. For around a couple hundred bucks you're getting a dual-channel wireless receiver, two belt-packs, two lavalier mics with windscreens and fuzzy screen, plus all of the needed cables and belt clips, plus a hot-show adapter and a soft zippered case! Come on, tell me you're not impressed, this is a great value; if it works.Performance. So, there are three aspects to wireless mic performance; 1) RF performance, 2) AF quality, and 3) Mic quality. While I haven't tried what some other buyers did, using the mics at 200+ feet, the RF performance has been outstanding. Since RF noise is generally a show-stopper, you need to have a strong and consistent signal with great rejection of other RF noise. This set has performed flawlessly, even in an office filled with Wi-Fi, 4G and 5G phones and across the street from a Fire Hall.Audio performance boils down to Noise, Dynamic Range, Distortion and Response. Monitoring on headphones, I thought the noise floor was a little high, but in reviewing recordings, I can say that it is well within expectations for any Prosumer application. Dynamic range has also been well within the range needed for our corporate videos, and consequent distortion is negligible. Of course since there's no "real" documentation we don't know if there's a limiter or noise suppression circuitry, but so far, no overloads. And finally, the mics sound like you'd pay $200 just for them. Sure, there's a bit of handling noise, but if you route the cables correctly and affix the mics so they don't rub against clothing, you're golden.As for build quality, everything's functional but you know it's a budget system. The battery doors are a little fragile and it's tough to get them to close smoothly, but that's minor. The belt clips are a little too stiff but work well. Display is good, backlight is time-adjustable, and the buttons are all good and offer tactile feedback. I like that the mic and line inputs on the belt packs and output & headphone outs on the receiver are all 3.5mm with screw threads to keep your cables in place. Nice touch. The hotshoe adapter is an unexpected bonus and the case is surprisingly well made and padded.With respect to features, everything you need is there, so long as you stick to the stock configuration. You can change radio channels if there's interference, adjust the time-out of the LCD backlight, enable and disable the mute function. On the receiver, you can also adjust the output level to better match the input of your camera or recorder. What you can't do is adjust the gain on the mic inputs, which isn't a big deal as long as you stick with the supplied mics.So, if you need a wireless mic rig for corporate or YouTube video production, live, recorded or online presentations, amateur theater or school productions, this is your ticket. Keep in mind that mics are omnidirectional, so they're best for controlled noise environments and low-gain live reinforcement, which includes most anything you'd buy a $200 rig for. No doubt the same PCBs are likely hiding inside a branded product selling for a multiple of what you'll pay for this. Enjoy!

The media could not be loaded. I create online tutorial content related to topics of audio, photography, filming and lighting. For my video creation needs, I mostly use wireless lav microphone systems so I can have the freedom to move around without tripping over audio cables. I’m typically filming myself with my camera or camcorder roughly 5 to 7 feet away from me and have a variety of Canon cameras to choose from, such as the Canon 90D DSLR, Canon M50 mirror-less, Canon G60 camcorder, Canon XF400 camcorder. For this simple audio test, I’m pairing the Comica CVM-WM100 Plus wireless microphone system to my Canon 90D DSLR camera with my favorite lens, the Canon 17-55mm f2.8 IS USM zoom. At the typical distance of 5 to 7 feet away from the camera and wireless receiver, the Comica CVM-WM100 Plus microphone works fine and the audio is crisp and clear. I realize this microphone has a rating of over a couple hundred feet distance, but I personally find that to be non-applicable for my own needs because I would never film myself from that far away. Even if I were to film myself from such a far distance, my face would be so tiny in the frame that you wouldn’t be able to see me, so there’s no point in doing that. Generally speaking, wireless lav microphone systems work better indoors than outdoors. Why is that? Because with indoor usage, a typical wireless lav microphone signal will bounce around the walls and come back to the receiver. But in open outdoor usage, there are no walls for the signal to bounce around, hence making it more difficult to maintain a signal from a longer distance. This is especially true when there is no line-of-sight whereby the transmitter is not directly facing the receiver on the camera, which means this can result in a dropped signal and gets worse over longer distances. But again, this is not applicable for my own needs for doing online video content whereby I am filming myself in front of the camera within 10 feet away from the wireless receiver on the camera. Of course, your needs may be different and your mileage may vary which depends on many factors. Therefore, I’m more interested in the practical aspects of a wireless lav mic, such as reliability and ease of use without too much fussing around with settings. The Comica CVM-WM100 Plus mic works well for my needs given the type of work I do. I generally only use 1 transmitter paired to the receiver, but I like the idea that this package kit comes with 2 wireless transmitters in case I have a second person that I want to film and record for audio. I find the transmitter to be very light weight and relatively compact. The light weight for both the transmitters and receiver is most likely due to the all plastic material construction. I can’t speak to the long-term durability of the product, since I have not had this long enough. The dimensions of the transmitter and receiver is a little bit taller in height than other similar systems I’ve used, I would prefer it to be a little shorter. But as mentioned, an advantage is that the unit is very light weight, even with 2 AA batteries inserted. Speaking of batteries, I prefer to use Eneloop rechargeable AA batteries which generally provide me over a few hours of usage per charge. In a way, I prefer to use AA batteries versus a microphone unit that has a built-in rechargeable battery. Why you might ask? As an example, my Rode Wireless Go microphone system has a built-in rechargeable battery for both the transmitter and receiver. But once the battery runs dead from continuous usage, it takes quite some time to wait for the Rode Wireless Go transmitter and receiver to fully recharge again. This is highly inconvenient and a waste of time. But by using AA batteries for this Comica CVM-WM100 Plus microphone kit, I can simply swap out dead AA batteries for freshly charged ones that only take a few seconds to do. That’s why I usually prefer using a wireless mic that takes AA batteries versus a built-in rechargeable battery. I hate waiting for dead rechargeable batteries to charge back to life again. This Comica mic is pretty easy to use, you really don’t even need to read the manual, especially if you have experience using wireless lav mic systems. It’s easy to wirelessly pair the receiver to the transmitter, this only takes several seconds. Once paired, you’re in business and ready to record. Only other things to do is to set the volume level to an appropriate level for your voice, plus attach the wired lav mic to the transmitter(s) and maybe attach the dead cat/kitten too. The package comes with everything you need to record 2 persons wirelessly. In addition to the one wireless receiver, you also get two wireless transmitters in the box, which also include two wired lav mics to insert into each transmitter along with a dead cat/kitten wind screen for each transmitter. Also included in the package is a very nice carry case that fits all the various items. The Comica wireless receiver comes with a simple hotshoe adapter to attach the Comica receiver on top of a typical camera that has a hotshoe (or coldshoe). The useful LCD screen and navigation buttons on the receiver and transmitters are helpful for setting up the microphone and adjusting settings as needed. Plus the decibel scale on the LCD screen is useful to monitor your audio level to make sure you are recording at the proper level (not too loud nor too low in volume). All in all, I find this Comica microphone to be a decent value, especially when Amazon sometimes offers a sale. If you are need of a dual wireless lav mic system to record 1 or 2 persons for creating video content, this Comica CVM-WM100 Plus model is worth consideration. Check out the attached short video review plus pictures of this product.

The media could not be loaded. The Comica CVM WM 100 Plus is a good, budget friendly alternative for those wanting to up their audio game. This setup allows you to easily record one or two people at the same time. Stand-out is the signal strength and reception. As you can see in my tests, I experienced no dropouts even when recording through multiple walls. The user interface and audio features are also quite good. All the cables and adapters needed to get going are in the box and it comes in a nice padded carrying case. The included lavaliere microphones do a good job for most uses but are only average in terms of sound quality. Also, it would have been nice to have a built-in Li Ion battery rather than having to use AA batteries. But overall, a really good product - highly recommended.
