GoPro 3.5mm Mic Adapter and a basic lavalier microphone to start recording narrations while I was riding. My biggest challenge in the setup was the location of the mic inside my helmet. In the first sample video, I had the lavalier clipped to the bottom fabric lip of my full-face helmet pointing up toward my face. This limited the microphone's usefulness to speeds below 55MPH, and I could imagine that threshold to have been lower if I didn't have a significant windshield on my motorcycle. I also had the microphone setting on the GoPro set to "Standard Mic+" which I found to be unnecessary because the sound was peaking and cracking, even at slow speeds.
In the second video, I adjusted the lavalier mic so that it was nested behind my helmet's rubber breath guard. I also returned the GoPro mic settings back to "Standard." That worked out perfectly and the mic sound was clear at all speeds, even during the short moment when I raised my face shield to scratch my nose. So for now, that microphone positioning will be my go-to when recording my voice with the camera on.

| Here's the lavalier mic's clip from the outside. I can't see it when I'm riding, but I do admit that it is a tad bit goofy to look at from this angle. |
