COMICABoomX-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. Just purchased this set of microphones and I think they work really well, super easy to connect to the device once you have the right adapters, most people will try to look for light inconspicuous microphones but they often forget that the small they are the less of quality you get however that’s not the case with these granted they are very bulky and big I don’t mind that if it means you get good audio from it. The sound quality is great and it comes ready to use. Compared to other mics I’ve had these come out on top. W purchase it will help boost production

I recently purchased the Comica BoomX-D D2 Wireless Lavalier Microphone System. I have used it in the field and I have been very pleased with it. I primarily produce travel videos and high-quality audio has always been a concern. To that end, I have invested in products from Zoom, Rode, Edutige, Adzen and Comica. All of those products have their applications, but what I needed was a small and high quality wireless dual microphone system that was suitable for run and gun voice-over narration. So, having had very favorable experiences with both Rode and Comica products, I compared the specifications and watched countless YouTube videos for both the Rode Wireless Go and the Comica BoomX-D D2 Wireless Lavalier Microphone System.After review, the Rode and the Comica 2.4G digital wireless systems both met my build quality and crystal clear audio reproduction standards. But that is where the similarities ended. Unlike the Rode Wireless Go, the BoomX-D is a dual-mic system. In fact, one might even say that it is a quad mic system. Because both of the included BoomX transmitters have 3.5mm TRS inputs for direct connection to a lavalier or other microphone and a built-in mic for handheld in-the-face interviews or for ambient sound recording.The combination of these two independently audio gain controlled transmitters, sending audio to the wireless receiver from the included and very high-quality Comica lavalier mics in either a full stereo or in two mono tracks is fantastic. Additionally, one BoomX-D transmitter can be connected to a lav and the second transmitter can be used as a hand-held or pole mounted interview mic. You can't do that with the Wireless Go.The advantages of two included transmitters with a receiver versus one transmitter and one receiver for basically the same price aside, the Comica BoomX-D system includes it all in one very nice product box. The BoomX-D system includes two high-quality lav mics. It also has two very effective dead cat wind muffs for the lavs. Comica has also included two removable foam wind muffs for the transmitter pickups. There is even an assortment of 3.5mm cables for Canon and Panasonic cameras, plus a TRS-TRRS cable and a Type C, USB charging cable.

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.
