Why do GoPro | DJI | Insta360 | Hate Motovloggers? Part 1

In a final attempt to try and fix the audio quality out of my action cameras for motovlogging.
I go though what I have tried, responses from these companies and the lack of support from people that actually receive these cameras for free to test.
Are they testing them to how they should be used? Or do they just follow the script in order to not ruffle any feathers?
The things I need to work out, Is the external audio setups on these cameras really this bad or is it just my helmet?
Do I need a new helmet? new camera? or both?
