Designed for vlogging, live streaming and near limitless expansion - Media Mod transforms HERO10 Black & HERO9 Black into a production powerhouse. It features a built-in directional mic for enhanced voice capture, 3.5mm mic port, HDMI-out for playback on external monitors, plus two cold-shoe mounts for lights, LCD screens or additional mics. Built tough and weather-resistant, even the wind is no match for this mod. The removable foam mic cover suppresses wind gust up to 20 mph (32 kph).
