Recording equipment has never been as easy to come across as it has been in the last so many years, making it incredibly simple for beginners to get started without spending thousands of dollars on high-end equipment. Wireless microphones especially since there are so many affordable entry-level options that sound great within the $100-$300 range (depending on the solution and what you need them for). The same options coming from a company like Shure or Sennheiser would easily set you back 3-6x this price (although they do sound better of course).
Here’s a wireless lav solution that is best fit for beginners looking to get a kit that works right out of the box while on the go. The COMICA Boom X-D Dual-Wireless 2.4GHz Lav Kit. Wireless from point to finish, coming with two microphones and a single dual-channel receiver that would connect to a mobile camera rig. Simply turn all three units on and you are ready to start recording.
All three of the units are tiny, as you can see in the above image where we placed a AA battery in the box. They are incredibly small, making them quite versatile when it comes to hiding them or reducing weight.
One way they reduced some of the size and weight is by building-in a rechargeable battery. Each of the three units charges via USB and lasts a decent amount of time (up to 5 hours of use time). So it will save you on battery costs as well.
There are minimal settings to play with making it very plug-n-play. There is no frequency or channel selection which makes it all the easier for beginners. This is also where these are quickly separated from pro solutions since anyone other than beginners may not find this acceptable to their needs if they plan on using these in RF-populated areas where they may run into interference. However, for beginners, this is one of the major contributors to the whole “turn it on and go” capability.
You are able to adjust the gain of each mic from the receiver, as well as switch between mono or stereo (one mic left and the other right, or both feeding to both channels). This is common with most wireless solutions and for post-editing sake, you should never buy a mic that doesn’t offer this. You also have the option of muting each mic (via the transmitter).
What’s nice is that both transmitters feature a lav mic with optional windsock, but they also work without the mic attached, thanks to a built-in microphone. This makes these quite similar to the Rode Wireless GO kit. Actually, these are incredibly similar to the Rode Wireless GO (only the GO doesn’t offer a dual receiver, therefore you need two if you have two mics going).
When it comes to what they sound like, the lav does produce the best result. The built-in mic sounds ok, but it is missing some of the body (a focus on mid-highs and highs). Attaching the lav brings in a little more attention to the mids and mid-lows (not a lot of lows though). The sound quality is decent, but it is tainted by a noticeable noise floor that you’ll have to be ready to edit out in post. It seems to be caused by electrical noise within the unit. To help get rid of it, you can crank the gain a bit on the receiver for both mics, then knock out what’s left in post. You can witness this in the following two samples where we did just that.
Using the built-in microphone:
Using the lav mic attached:
They do have a really good range to them, making them easy to use outdoors without having to be right up and close to the action (in case your situation forces your camera to gain some distance). So you can get around 150ft away or more from the receiver unit (direct/unobstructed line of sight).
The only thing that affected the score for us was the noise floor and price range. For this price range, we expected the noise floor to be much lower than it is. You shouldn’t have to edit anything out in our opinion (outside of some OCD stuff).
The audio needs a little more “oomph” to the resulting record and the price isn’t competitive. For the same price range, you can invest in a solution that can sound better and likely even offer the ability to switch between channels/frequencies (like Comica’s own Comica CVM-WM100 Plus kit)
For what they are though, they are still a decent microphone solution for beginners who don’t want to fuss with anything. Just turn them on and go.
