By the way, sound is bad on all of them, even the most expensives, like the GoPro. Nature of the beast. Either the wind, street noise, tire hum, motor noise, etc.
If you use your phone with the headset you got with it, it has a built-in mic. Muffle it and speak normally, works pretty good.
Here is one fella I follow on YouTube, Kobevision, rides à Radrover. He records his back and forth from work. He's got this new Samsung Gear 360d camera. Look at this video on your mobile, touch the screen, swipe around and see it all. Very, very cool.
He has literally dozens of good videos.
Oh... And he works at Tesla. How cool is that?
