Audio recording has many uses, from capturing your voice on a YouTube or Twitch gaming stream, to talking with colleges over Zoom, to even giving a presentation to an large audience where you own voice may not be heard from the back of the room. Wireless audio capture has grown over the years as the demand increase for recording your audio without being entangled or restricted by wire cables.
The KM-G130-1 2.4G Wireless Lavalier Microphone comes from KIMAFUN, who is a Chinese professional microphone company that supplies microphone technology for recording musical instruments as well as for on-person recording.
The KM-G130-1 is an all-in-one-solution for transmitting audio wirelessly from its lapel microphone, into a transmitter, which then beams wirelessly over a 2.4G signal to a receiver that can be plugged into a variety of recording or audio devices, such as a MacBook, iPhone or iPad, to even a DSLR camera or outdoor speaker.
In the box, you get a handy carry case to keep the transmitter, receiver and all its accessories together. Inside the case, you get the wireless transmitter, which has the lapel microphone permanently attached to it via a 1.15m long cable.
The wireless receiver has a 3.5mm connector on one end, which you can insert directly into a 3.5mm port on an iPad, desktop computer or laptop device that will be used to record or receive the audio from the microphone that’s attached to the transmitter.
If you don’t like to stow the transmitter in a pocket you also get a strong plastic and metal clip to conveniently attach the transmitter to your clothes. There’s a 50cm long USB-A charging cable that splits into two 20cm long Micro-USB cables to charge both the transmitter and receiver.
A USB-A adapter for PC or Mac desktop computers and laptops also comes bundled, which splits the microphone and headphone into two separate input ports. You also get a 3.5mm splitter cable for use with iPhones, iPads and DSLR cameras. For some smartphones and Apple devices you will need a 3.5mm adapter to use this cable, such as the Apple iPhone Lightning to 3.5mm adapter.
You also get a spare microphone spoffle and 6.35mm adapter that will allow you to plug the receiver into such devices like power amplifiers, audio mixers and outdoor speakers. And finally, there is an instruction manual, help leaflet and a customer service card.
Setting up the 2.4G wireless Lavalier microphone is super simple. You first attach the receiver into an audio recording or audio projecting device. This can be a number of things, but for me, I first used the receiver with my iPad Pro, using an Anker USB-C to USB-A adapter. I then attached the bundled USB-A adapter into the Anker cable and turned the wireless receiver on via the on and off switch that’s located on the side of the wireless device.
You next attach the transmitter to your person, by running the cable to a sufficient location on your chest or collar, and attach it by using the attached metal crocodile clip. You can then stow the transmitter into a pocket or use the bundled clip attachment to clip the transmitter onto a back pocket, a strap or another part of clothing that’s out of sight.
The transmitter itself has a few extra controls located on it. As well as the On and Off switch, you have some recording up and down volume buttons, which helps you alter the microphone’s audio output to the receiver without adjusting the microphone levels on the receiver or device end.
Once the transmitter is switched on, that’s it! After around 2 seconds, both transmitter and receiver begin to talk to each other over a stable 2.4GHz wireless transmission and you are now sending audio to your recording or output device with low interference and short audio delay. A small blue LED light on both transmitter and receiver illuminate to help assure you that both are powered on and are in sync.
The KIMAFUN wireless microphone has decent performance credentials. It is able to transmit up to around 30-50 meters in range. Personally I can’t quite think why you will want to be that far away from the receiver, but it’s good to know it has that kind of range.
Both devices come with their internal lithium battery pre-charged. Each device has a total capacity of 500mAh, which gives around 6-8hours of recording time, and you can charge them back up using the bundled USB splitter cable within around 3-4hours.
Sound quality from the KIMAFUN 2.4G is pretty decent for its price range. I found issues with the USB-A to 3.5mm headphone and microphone jack dongle, in that it gave really low audio levels that required me to increase the volume by 400% in iMovie and it could have still wanted more. It also produced a considerable audio delay along with its captured video, whereas connecting the receiver to a Turtle Beach Amigo II dongle didn’t perform any of the same audio level and sync issues. Trying other cable connections didn’t have any of these issues, with the 3.5mm splitter cable connected, my iPhone did a great job with recording audio levels and its quality was very clear.
The microphone performance can vary greatly on where you place it on your person. Attached to a shirt or collar under your chin gave a little too much of a distant result, whereas if you had the microphone angled towards your mouth, it gave a more pleasing audio level and quality. This is due to its condenser style of microphone, which receives audio much better when it’s cast directly into it rather than around it.
The KIMAFUN 2.4G wireless microphone retails for £45.99 from Amazon UK or $59.99 from Amazon US and other regions or $42.29-$44.99 from AliExpress at the time of this review. It’s a little investment over much cheaper, non-wireless Lavalier microphones, but this is a decent price for a wireless microphone recording solution, especially when compared to popular wireless receivers like the RODE Wireless GO, that retails for over £170. So its price and its performance is very competitive.
It’s a shame there is no display to visually show audio levels on the receiver end, and I would have liked to have seen a detachable microphone cable so that you could plug in other devices into it and be able to record audio from them wirelessly.
If you are looking for a cheap and decent wireless microphone solution for recording audio at a distance, where a conventional microphone or shotgun microphone simply isn’t going to pick up your audio, be sure to check out the KIMAFUN 2.4G Wireless Lavalier Microphone.
