Comica BoomX-D2 - Wireless Microphone System for Cameras, Camcorders, Smartphones, Laptops, Compact Wireless Lavalier Lapel Microphone with Safety Audio Track, Noise Reduction, 328' Range, Low Latency

The first wave of ultra-miniature wireless microphone kits arrived from RODE with their Wireless GO, and the Comica BoomX-D kits build upon that amazing Aussie innovation, saving more money while adding features, especially in this kit with an additional transmitter for simultaneous capture of two wireless sources fed into one receiver for stereo recording (multiple GO's cannot do that): the left channel gets one discrete transmitter, and the right channel gets the other one. It's really easy once you're in your editing program, to make the left channel a separate mono track, and the right channel its own mono track, for independent volume control and editing later on.I like that all three internal lithium batteries are charged via USB-C (not old micro-USB) connections. You can even bus-power the units while they're in operation. The spring-clip on the back of the receiver cleverly can double as a hotshoe mount too, because it's the standard width and thickness, staying especially tight on the camera since it's spring-loaded. Compared to the GO, these transmitters come with cabled lavalier microphones too, adding the option for better and closer-in audio that's hidden. And instead of screw-down connectors like on Comica's RF wireless packs (which can wear down over time and risk wire fault), Comica has added a clever new "hook insert" system that latches down connectors enough for peace of mind -- but also pop out if a wire gets snagged hard. Besides these cabled lav mics, I still like the run-and-gun option to just quickly clip the unit onto talent, on the go, without wiring up. The internal microphones on the transmitters sound OK -- not as good as the GO, but decent enough when necessary.Since the wireless signal uses unlicensed spectrum, just like Wi-Fi, it's a little risky and I got occasional dropouts when wandering around downtown New York City which is extremely congested. I look forward to the arrival soon of devices that ride more reliably on Wi-Fi 6, but for now, this technology works in most environments reasonably well. When capturing wirelessly, you always want to have a wired backup plan anyway -- and the cool thing here is, you can simply plug either of those included lav mics straight into your camera, in case you need to, or want to.I appreciate the colorful displays too: not just because they look nice and bright, but because you can see separate functions clearly at-a-glance (when there's so much else to worry about). You can get instant confirmation of audio activity and levels no matter where you are, from meters on the transmitters, to the receiver where you can adjust each volume level separately from that master position. The only negative I could find, is that when you're charging any of the three units, or bus-powering them during operation, the battery level icon doesn't change: you can't see confirmation that it's charging. I've never seen that absence on any other product. Hopefully it's fixable via firmware someday.One last bonus, easily overlooked, is that Comica includes an attenuator cable (they normally cost an extra $30 or so), identified by an orange connector. It's important for adjusting compatibility between some microphone ports and line-level ports (in both directions). Certain cameras and other products vary widely at this impedance level, so the cable can really get you out of a bind.

The media could not be loaded. The comica BoomX-D2 is a wireless lav microphone system that allows you to record audio from two sources with one receiver. It uses 2.4GHz digital transmission to deliver clear and stable sound quality with low latency and noise reduction. It is designed for mobile journalists, videographers, vloggers, podcasters and live streamers who need a compact and easy-to-use solution for their audio needs.The system comes with two transmitters that have built-in microphones and lav mics that can be clipped on your clothes or attached to your camera. The transmitters also have locking pins that prevent the mics from falling off. The receiver has a dual-channel mode that lets you choose between mono or stereo output. You can also monitor the audio levels and battery status on the OLED screen.The system is compatible with smartphones, cameras, camcorders, laptops and other devices that have a 3.5mm audio input jack. You can also use an adapter cable (not included) to connect it to devices that have a lightning or USB-C port.The system has a built-in rechargeable battery that can last up to 5 hours on a full charge. The comica BoomX-D2 wireless lav microphone system is a great option for anyone who needs a simple and reliable way to record high-quality audio from two sources wirelessly. It is lightweight, portable and easy to set up. It offers good sound quality and low latency. It is also affordable compared to other similar products on the market.

The media could not be loaded. Once in a while, I cover a product in a review I can't find really any fault with. And this is one of them. I have gone through so many Mic systems I honestly got bored of them, but this one caught my eye. Let's go through just a few basics since the video covers most everything. Ok, so let's cover the main features. It has audio monitoring which is huge for those who have camera systems that decided to leave that out. It has channel separation between mics which is super convenient between mics if you want a backup or simply want left and right channels for an interview or something. USB type C charging is a joy to have as well as a battery monitor on the mini LCD.Having a built in monitor for each transmitter is REALLY a hard to find feature which just makes so much sense.But really all these things are already on paper and what you really want to know is how does it sound. Honestly, it is some of the cleanest and static-free sound I have ever gotten out of a wireless Lav Mic system. The audio is pretty basic and requires a little punching up but is SUPER clean and easy to work with which is what matters most. Comica has made a fantastic compact mic system that serves the needs of all with its extremely ell thought out design.Bonus fact: the clip on the back of both the transmitter and receiver both fit the 3/4 cold shoe mount on all cameras.

I've used these mics a few times and they work fine. They can be a little glitchy at times, but I'd say 95% of the time I've had no issues. The sound is decent, a bit tinny at times. Be aware the mics are omni-directional so they will pick up other sounds around the person wearing it, and aren't all that great in big open space rooms. You will get the echo effect if the room isn't dampened. If you use the provided lav mics, the sound is dampened a bit, and you'll have to make adjustments for that. I pretty much have them as an emergency back-up at this point should my main wireless mics fail. For wireless 2.4G mics though, I would, however, recommend getting the Rode Go mics over these in a heartbeat...they are much more robust in sound quality, and their lav mics are great, making them a very secure back-up. Plus their is a new dual-rode mic assembly made by SmallRig that will give you the same functionality as these 2-in-1's. Either way, these Comicas are good for the price, and they are decent for the amateur or as a back-up set for pros in a pinch.
