When your breathtaking videos need audio to match, grab the Sennheiser MKE 2 Elements: a waterproof action mic for GoPro HERO4 cameras. Great for filming while mountain biking, surfing, snowboarding, and more, it’s every bit as robust as your GoPro. This mic is waterproof down to 3.3 feet, and while it won’t record sound while submerged, it’ll pick up where it left off as soon as it resurfaces. Plus, getting set up is easy: Simply connect the mic to your camera using Sennheiser’s custom BacPac Backdoor, and you’re ready to capture the action.

Don’t just take our word for it. Gear Institute says, “Far from a standard plug-in external microphone, the action mic is a complex piece of audio equipment that actually improves the frequency range and response of the GoPro HERO4’s onboard microphone, giving the user crystal-clear audio never before heard on an action camera.”
