COMICA CVM-WM300A 96-Channel UHF Wireless Lavalier Microphone System Compatible with Cameras, Camcorders and Smartphones, Perfect for YouTube Podcast Vlog Video Recording and Interview(2TX+1RX)

The media could not be loaded. The main I reason I got this wireless kit, is the ability to feed two transmitter packs, into one receiver that has twin antennas, and an infrared port offering one way to synchronize the transmitters with the receiver. The 3.5mm output jack is stereo, which is especially important because you can make it allocate one transmitter to the left channel, and the other to the right. The receiver and each transmitter also have a micro-USB port, for charging their internal lithium batteries. Unfortunately there's no backup alternative to get power from alkaline batteries, but you can always try tethering a USB power bank.I like how there's not only the usual belt clip on the back of each transmitter, but also a 1/4"-20 mounting screw socket, which is something you normally only see on the receiver side. The specified frequency range of 520-580 MHz tells you that this system uses older UHF frequencies, which have pros and cons compared to the newest systems by Rode and Sennheiser, for example, that use 2.4 GHz spectrum. The signal travels farther at UHF, but the frequency hopping to avoid interference, is less sophisticated.At the transmitter, you can specify the impedance at the audio input, between microphone and line level. You can also decide whether to add a low cut filter that can reduce hum or wind noise, at low intensity or high intensity. And you can boost each radio's power output to a high setting if necessary, using more battery. There's a muting option in the menu, but it's easiest to just press the power button with one tap, and you'll see the top Audio light turn red.One really important menu option on the receiver is to select between Stereo output and Mono output. If you're only using one transmitter, then Mono is just fine, and you'll get the same audio in the left and right channels at the physical stereo miniplug output. But if you're using two transmitters at once, then it's wisest to choose Stereo so that one transmitter is on the left side, and the other on the right -- this way, you can control the levels separately later on. But you'll need to be really careful in post-production, to reallocate those channels onto separate tracks so they aren't sounding hard-left and hard-right in the final export.Another nice feature is the ability to power off a transmitter remotely from the receiver. And you can also set the volume at this preamp phase, especially to avoid clipping in really loud environments. Plus, there's a bluish backlight on the LCD display, but to save energy, it automatically turns off after a time you can set.I do hear a small quality difference in A/B tests, sounding better on Rode's wireless system, probably owing to its own premium lavalier microphone, so it's worth getting better lavs and trying that out on the Comica transmitters. But the versatility of being able to get two separate transmitters feeding into one receiver, is the best feature of this Comica kit. Other folks are just starting to launch products with the dual feature, but still at a much higher price point. The all-metal chassis on each of these Comica units feel durable, and performance seems adequate, so you might want to save a few bucks and give these a try.

The media could not be loaded. I'm so happy with this system! I'll be adding to this review as I learn and test more but I wanted to get something online to share because this system rocks! I create YouTube videos and needed a wireless system to help me create my content. I don't know a lot about audio and really was looking for a high quality and easy to use system. Bingo, this is it!The system comes in a sturdy case that contains all the gear. Both the transmitters and the receiver are built with a metal case that blows away the plastic cases most of these systems are built with. Before I started using the gear I charged up the batteries in everything. This was very cool to see, rechargeable batteries and not needed a bazillion AA's HAHAHAHA!First I mounted the receiver to my Cannon T5i hot shoe and plugged it into the mic plug of the camera and turned it on. Than I attached one of the included mics to a transmitter, flipped that bad boy on and everything worked!The audio quality was amazing and exactly what I was hoping for. In the final mix I added a limiter to the tracks because my voice fluctuates a bit but that's normal for all my recordings.Attached to this first pass of my review is a picture of my setup. I'll also post more pictures soon as well as a quick clip from the first video I recorded with the system.If you are looking for a high quality cordless mic system then look no further. I can't say enough good things about this one!----- UPDATE Oct 29th 2019 -----I just added a snippet of video from an actual recording I used on YouTube. Very happy with this system and I think it sounds great! I can't post a link to the actual video here but if you did happen to check it out you will read quite a few positive comments from my subscribers giving the sound from this system a thumbs up. Next I will test a few of the features regarding both transmitters running at the same time. I'll update this review with my findings.

This is an excellent sounding wireless mic system and it's easy to use. The cases on these units are nice solid metal a big plus for me. The sound is rock solid and to me the noise reduction is fantastic. One of the best features is that it's so easy to use. Typically, just turn the transmitter and receiver on and start using it. The only thing that I would improve is the charging port. It's micro-USB and in these days USB C is the way to go and would be a plus. Overall, this is a fantastic system.
