COMICA BoomX-D2 Wireless Lavalier Microphone, 2.4G Dual Lapel Mic with 2 Transmitters, Noise Cancellation, 656ft Range, Compatible with iPhone, Android, Camera, for YouTube Video Recording Streaming

Initial Review Date: 2023-OCT-16I was looking for a 2-mic setup and I saw these while browsing. I'd never heard of the brand before. In the past, I'd typically stick with more recognized brands like Sennheiser and Samson. But I needed something in a pinch and based on the reviews and price, I thought I'd give them a shot.My testing thus far has been limited to about 20 minutes of tinkering with them connected to my Canon EOS R3. More testing (and a review update will follow later.)Thus far, I'm VERY IMPRESSED with the quality of these units. They came showing a full charge and they were already synced with the receiver. The built-in mic and the corded lav mic both perform equally well, which surprised me. I didn't notice any significant drop off in the vocal frequency range. It wasn't too bright nor was it too deep or muffled. It was just about exactly as I expected! I'm going to try using it as mic for video recording and narrations directly into my computer. From there, I'll be able to compare them objectively to other mic setups.For all intents and purposes, I believe these are going to be a successful replacement for my old (first gen) Sennheiser eW100 units and Samtron 32M units.General notes / observations:1) Pay attention to what cord you are using to go from the receiver unit to your input. I didn't pay attention and thought at first I had a problem. Well, I mean, I did have a problem. I was using the TRS cable intended for a phone. This cable has a tag on it, a gray-colored connecter, and a slightly different plug. So there's 3(!) things that distinguish it from the cable required for cameras. This is also noted in their product pictures supplied in the Amazon listing.2) Stereo and mono work as advertised. When used in Stereo, the sending unit marked "A" is the left channel. It's not too hard to figure that "B" is the right channel.3) They are very lightweight! But they'll probably still tug a little on lightweight fabrics.4) The sending units have something notably magnetic in them. Put them back to back and you'll see them push away from each other. This probably isn't a problem in nearly 99.9% of situations. But it's just an observation.5) These are pretty much plug & play right out of the box. Little-to-no learning curve required!

The media could not be loaded. This Comica BoomX-D2 is an ultra-compact digital wireless microphone system which is unique in its clip’n’go versatility, incredibly compact form-factor, and unmatched price accessibility compared to other model such as the Rode Go. It’s the perfect wireless mic solution for content creators in all disciplines: filmmakers, on-camera presenters, newsgatherers, vloggers and more !I am comparing this microphone system to the Go since before to buy it, I was considering buying the Rode Go instead. However, after some research about the Rode, I found out that it has a major defect; When you remove the external microphone on the Rode transmitter, the internal microphone does not work any more ! Plus, with this set I was getting two transmitter (the microphone), a bunch of TRS/TRRS adapter AND two external Lavalier style microphone. When with the Rode they only give you ONE transmitter & receiver, and that's it. The rest was an extra cost separate accessories.So I bought the BoomX-D2 from Comica instead, since it was looking promising. And wow, this system deliver as promised, and yes as expected with the Comica system, I had NO issue what so ever when switching from the external microphone to the internal one, and vice versa.Ultra-compact and ultra light (TX is 30g and RX only 29g), the Wireless transmitter acts as either a quick and easy clip-on wireless microphone, thanks to a high-quality built-in omni-directional condenser capsule, or as one of the world's smallest belt-pack transmitter for a Lavalier microphone via the 3.5mm TRS input. The BoomX quick clip-on capabilities make it perfect for run-and-gun journalists and vloggers in the field: never miss the action as it happens – no cables and great sound.The receiver is just as compact, which makes your rig that much easier to carry and facilitates mounting on a range of camera gimbals and stabilizers. It clips easily onto your camera strap or an item of clothing. The supplied 3.5mm TRS output cable plugs into your camera’s audio input or, (with the relevant available adapters - NOT included with this set), into your recorder, GoPro, iPhone etc.One of the best functionality with this system, is the fact that, because you have two microphone transmitter for one receiver, you can record your audio input in STEREO as well ! The sound quality from the integrated microphone is also great, and even better than when using the external Lavalier mike in my opinion. As for the battery life, I charged those only once and used them all day, and yet I didn't have to recharge neither of those.Well, I can probably talk all day long about this microphone system, but let do a "good and bad" section for those reading my review who want to go straight to the point.GOOD:- Operates as a clip-on microphone or belt-pack transmitter for a lavalier/headset microphone- Built-in omni-directional condenser microphone delivers broadcast-quality sound- Delivers crystal clear audio under any conditions, even in locations with dense Wi-Fi and Bluetooth activity like shopping malls, conventions, hotels etc- Tested at 70m range (line-of-sight) without an y loss of signal, but optimized for shorter-range operation in congested radio-frequency environments- TX and RX have built-in rechargeable batteries, charged via USB-C port- Rated up to 5 hours on a full charge, but yet never run out of battery during testing- Auto battery-saver mode- Super-lightweight and ultra-compact: TX is 30g and RX only 29g- The transmitter and receiver pair right away, as soon as they are both power up- Signal not interrupted by turning your back to the camera/receiver- LCD screen are bright and easy to see, even under sun lightNOT SO GOOD:- The auto battery-saver mode dim the LCD screen automatically after a few second, which can be annoying when trying to read the screen info, and there are no setting to disable this feature. However, the screen will turn back to full brightness when any button is pressed again.

I’m a fan, doing small projects with my church and for my own business it’s a perfect fit. I use this on an external recorder as well and it is perfect for talking head shots/interview style or more. Range is great as long as there in a straight line with nothing dividing. You can have a wall in between you and the sound at close proximity. Clear sound and easy to work buttons. Mine is a few years old and working great.

Works well with my laptop and Logitech 922 camera, but sometimes a bit difficult to get it to record correctly. May be my own inexperience though. Overall good sound quality. Definitely worth the price. Easy to setup and connect. Small and light. Includes lavalier mics, which is a perk.
