Stereo omnidirectional microphones that were designed specifically for GoPro's HERO3, 3+, and 4 cameras and allow for easy capturing of high-quality audio to accompany the videos. They are incredibly easy to use - just place them in your ears and connect to the mini-USB jack on the HERO camera. The natural binaural effect produced by ultra-small condenser microphone units provides a first-person audio perspective, delivering a hyper-realistic 3D sound experience. Ideal for web content creators and GoPro hobbyists, these microphones bring an extra dimension to action and location videos, giving viewers the sense of actually being there. Their open-air structure allows outside sounds to reach the ears, providing safety while recording in crowded environments. The microphones are powered by the connection to the GoPro camera, eliminating the need for batteries or external power. Included clip mounts enable use for webcasts, interviews, and music. 4 pairs of ear pieces (XS, S, M, L) and two windscreens are also included. Frequency response: 20 Hz-20 kHz.
