Saramonic SR-GMX1 Clip-On Omnidirectional Lavalier Microphone for GoPro Hero4 and Hero3



There’s no question that GoPro cameras are amazing at capturing action, but their built-in microphones sound terrible, especially when you’re talking to the camera. However, if you use the inexpensive Saramonic SR-GMX1 wired lavalier microphone with your GoPro, your videos will have rich and clear sound, even when you’re traveling at high speeds.

Note: The Saramonic SR-GMX1 is not compatible with Hero Basic and Hero4 Session
