My package came wrapped this way. The packaging is a lot weirder than I expected. They probably spent less time with that. I’m glad they come in this beautiful hard case porch which can practically fit all important accessories. Speaking of accessories, I went with the double transmitter package. And with that, we get 2 external lapel microphones, a 3-in-1 USB type C charging cable, 2 deadcat furry windshields, TRS to TRS and TRS to TRRS audio cables, 2 transmitters and a single receiver.

For the specifications, this wireless microphone adopts an advanced 2.4G, transmitting between 30-90m. 90m if there are no obstacles, one clear line of sight and 30m if there are obstacles like trees and buildings. The charging cable is fairly long enough. It features a USB type A at one end for universal compatibility, and 3 USB type C at the other end. This allows charging both transmitters and receiver from one power source.

Both transmitters and receiver are made of plastic and come in black only. The transmitters come with an RF Frequency band or between 2400-2480MHZ and a transmission delay of 8ms. Each weighs 20g/0.7oz. At the top of the transmitter are the in-built microphone, audio port for external microphones and the paring and battery indicator. On the left are the power button and the USB type C charging port. The right side houses the reset and mute/pair button. It also comes with a clothing clip which you can easily attach to your shirts or the hot shoe mounts on the camera. The furry windshield is small and easily detachable as well.

The transmitter has an in-built battery of 300mAh and 350mAh for the receiver which both charge at 5V via USB. They say the battery can last up to 7 hours, but this part wasn’t clear. I noticed even though the battery life on the receiver is 50mAh and weighs 5g more than that of the transmitter, the battery life on it, was draining much quicker. I supposed it was so because of the TFT display on the receiver. Speaking of the display, it is bright enough for usage indoors but on a broad day in the sun, you would struggle to see anything. Fortunately, if sight isn’t good enough, then hearing should help out. The receiver has support for headphone connection for real-time monitoring. You would know it’s on stereo when you connect headphones and hear independent sounds on the left and right, and mono when you hear the same exact sound in both headphones at the same volume.



The in-built microphone is an omnidirectional one which can pick up sounds from all directions and reproduce them clearly. It also does well with reducing plosive sounds, background noise and wind noise, especially when you have this dead cat windshield on.

For the receiver, here’s how it looks. We have a min display up front with the audio in and out ports on the left. The USB type C charging port, power button and reset are all on the right. Then finally at the bottom are the paring/volume control buttons. These 2 buttons are used to control the audio levels of the microphones, from level 1 to level 6 on either.

On the receiver, the power button is on the right side. You would have to press and hold the power button for about 5 secs to turn the display on. The transmitter’s power button is on the left side. You would also have to press and hold for about 2 secs to power it on. The first time connecting both transmitters, you would have to press and hold volume control buttons on the receiver to set it into pairing mode. Press and hold the pairing mode on either transmitter to connect that also to the receiver. As you can see here, both transmitters are sending audio to the receiver in mono. A single press of the power button on the receiver switches between stereo and mono modes. As you can see in the background the audio from either transmitter spikes on the receiver’s display. Once the receiver is turned on, you’ll be able to see the battery life of itself and any other transmitter connected.



The sad thing about the audio cables is the fact that they are too similar. It’s too easy to confuse one with the other. The input ends are practically the same. It’s only when you bring the connecting ends closer to each other that you notice the difference. The one with the 3 stripes on the pin is the TRRS connector and that is for smartphones. While the other 2 stripes are the TRS connector which is for cameras, camcorders and other microphones. The audio cables I get with my BOYA BY-MM1 shotgun microphone, for instance, are never mixed up. Apart from not being identical, they even include labels on the TRS to TRRS cable to let you know which connecting end goes into the smartphone.

With the TRS to TRRS cable, you connect one end to the receiver and the other end to your smartphone. I used my Samsung A02s for this demonstration. Once you insert it, you would receive a notification to show that an external microphone is connected. The same applies to the TRS to TRS cable, you connect either end to the receiver and the other end to the mic input on the camera or camcorder. Unfortunately, this camera does not come with an audio output port for monitoring audio. But the good thing is that receiver itself, comes with an audio output port which you can connect to a 3.5mm headphone to monitor your audio.

Here’s how it sounds in different scenarios
