Gopro 5 vs 7 Video and audio test plus GoPro 7 with external mic

Video stabilization and clean audio, two big improvements from GoPro ver 5 to Go Pro ver 7. After my last test with the external microphone on the GoPro 7, I don't really see the need to use one at this time. Without the external microphone, the package is more compact, fewer parts and fully weather/water sealed to 33 feet.
