The Polar Pro Promic GoPro Microphone Kit is a custom external stereo microphone that attaches directly to the GoPro. It provides better sensitivity and higher fidelity than the GoPros built-in microphone - ideal for concerts, interviews, motorsports where audio is as important as video. On the HERO2 it plugs directly into the 3.5mm mic input, and for the HERO3 and later models there is a right-angle 3.5mm to mini-USB adapter included. The microphone powers from the camera and a removable windscreen is included to help reduce wind noise when filming outdoors.Features:Stereo pick-up pattern - ideal for capturing ambient sounds and atmosphericsCustom right-angle adapter for HERO3 and HERO3+ includedPlugs directly into HERO2Includes Removable Foam WindscreenMicrophone powered by GoPro - no batteries requiredCompatible HERO models include: HERO2, HERO3, HERO3 White Edition, and HERO3+ Silver and Black Editions.
