Hey, I've already bought an action camera and I plan on using it but its sound recording quality isn't too good. I was wondering if anyone knows a microphone that is small not too expensive and has good sound quality. I wan't to be able to record the background noises too, like a waterfall or people talking in the background. If anyone knows a good mic that would be sufficient for this please reply, thanks. By the way, I am using the Contour +2 as my action cam.
