Hello Dash Fast,
I was sent a “production” A119 Mini for test & review on June 15, 2022. The low audio volume level was one of the first things I noticed, and reported it to my Viofo Representative. Viofo released a firmware update to increase the volume level, but it did not work. Later it was determined the microphone was the cause, and they decided to replace / upgrade the microphone with a different type / kind.
Another notable upgrade is they increased the size of the heat sink to dissipate more heat. Viofo refers to these A119 Mini’s with the new microphone, and bigger heat sink as “2nd batch”.
How are we supposed to tell the difference between a 1st batch, and 2nd batch?
I don’t know.
Here are 3 videos to demonstrate the audio quality
1.) The first video in my review of the A119 Mini, (just watch the first 10 seconds for the audio example.
2.) The second video is my review of the A229 Duo, (just watch the first 10 seconds for the audio example.
3.) The third video I mounted the A119 Mini to the rear window in my car, and discovered despite the low audio volume for picking up conversations, it is excellent at reproducing wind noise. Lol
