Build and Handling
The M-9 kit transmitter and receiver are both around the size of a packet of cigarettes – although be honest it’s a long time since a handled one of those! 
They feel nicely built, but not the sort of thing that you’d want to drop onto a concrete floor or step on.
It’s good to see that the transmitter’s 3.5mm mic port has a thread so the mic can be locked and not accidentally disconnected.
Performance
M-9 Microphone enables great-quality audio recording. The signal is also maintained well over the 80m range, which is much further than I usually want to get from my camera. Objects coming between the transmitter and receiver can reduce the range, so it’s worth running a quick test if you want your talent to emerge from behind a wall or something solid.
With the lavalier mic clipped to my t-shirt, I found that the Filmmaker kit did a nice job of capturing the sound of my footsteps on a gravel drive, while still keeping my voice clearly audible. It makes for a natural sound.

FINAL THOUGHTS​​​​​​​
The word ‘wireless’ can often instil a sense of fear or foreboding. Will it be easy to set-up? Will you be tapping in passwords or scratching your head trying to make the two parts communicate with each other?
As with the K&F K-9 Microphone is very easy to set-up and use. The transmitter and receiver connect automatically and they stay connected. Even if you should wander out of the 80m range, or a large solid object gets in the way, they reconnect quickly once they are back within range. 
They have and excellent battery life with USB-power back-up. These aspects, plus the greater range, give the microphone some advantages.
It’s a cheaper and quality wireless microphone. 

WHAT I LIKED
- Excelent Audio Quality
- Easy to Work
- Good Distance Working

WHAT I FEEL COULD BE IMPROVED
- The antena could be inside
- it’s not possible to add additional transmitters to enable more than one mic to record to a single camera. That would be great for conversation and interview situations.
