All the GoPro cameras come with a built-in mono microphone.
It works but to take your videos to the next level you need an external microphone for the best quality.
This is not going to give the same quality the more expensive mics but will give you the sound you need for the recording of spoken voice.
The natural binaural effect provides a first-person audio perspective.
Perfect for vlogging.
Made to be used with GoPro® Hero [2,3,3+ or 4] camera
