K&F Concept M8 UHF Wireless Lavalier Microphone REVIEW

For quite some time now, I’ve wanted to add a wireless microphone set to my camera set-up. I hate having to be tethered to my camera and tripod with a microphone cable. I also prefer using a Lavalier microphone rather than a shotgun microphone because people always seem to be shouting when an on-camera shotgun mic is in use. With that in mind, I’ve really wanted a high-quality, but budget-friendly wireless microphone set. I ended up finding that with the K&F Concept Wireless Microphone Set.


This set is designed for use with professional photographers, videos, news coverage, lectures, and a variety of other occasions. The wireless transmission can reach up to 70 meters without any obstacles. The receiver and transmitter are only 85g each and they are very easy to wear or carry. The set uses UHF frequency and complex interference-free circuit. There are 6 preset channels available with strong anti-interference capabilities. It is possible to use more than 4 sets of devices can be used simultaneously without interference. The set uses WNCR noise control technology and will auto mute if no signal.


The wireless set consists of a transmitter, receiver, hot shoe mount, and a unidirectional Lavalier microphone compatible with most modern Canon DSLR cameras (Rebel T6S, T6i, T5i, T4i, T3i, T2i) with a 3.5mm interface. Both the receiver and the transmitter require 2 x AA batteries (not included). The battery door reveals not only the battery tray but also button controls for channel selection and volume control (receiver only) and a switch for selecting aux or mic (transmitter only). Each pack is made out of heavy-duty plastic. There is a metal clip on the back that can be used to attach the pack to a belt or pocket. K&F Concept includes a hot shoe mount that snaps onto the metal clip on the back of the receiver.

The battery doors are a bit stiff and they can be difficult to open. This is really the only criticism I have of this set. Because the plastic clips that lock the doors into place are hard to open, I’m concerned that it will eventually snap off. For the most part, you would only open the door to change the batteries, but since there are button controls on the inside of this set as well, it’s a little concerning that the doors are so hard to open.

I love how simple this set is to use this set. You add the batteries, hold in the power button until the LCD lights up. From here, you make sure that both the receiver and the transmitter are on the same channel. On the receiver, you will plug the extension cable in and then attach it to the microphone jack on your camera. On the transmitter, you will plug your microphone into the mic jack and make sure that ‘mic’ is selected on the mic/aux switch. At this point, you start recording. It really couldn’t be easier.

When I recorded some audio of my fiancé talking about how the kit works. It was easy for her to attach to her shirt and record her video. I was sitting approximately 8–10 feet away from her with the camera when I recorded her. The wireless set didn’t have any issues with the distance and we successfully recorded audio well with it. The only issue we really had was some over-modulation from the Lavalier mic. We tried another microphone to see if it was the equipment or user error and we found that while the volume on the mic was better it wasn’t perfect. So, we determined that the level on the mic needed to be adjusted. This is something that needs to be considered carefully before you start recording.


The K&F Concept Wireless Microphone Set is a great option for a wireless microphone kit. It is budget-friendly and compact enough to work with any on-the-go kit. I can recommend it based off of its ease of use and low cost.
