How to Improve Your Helmet Mic Audio for GoPro or DJI Action Cameras
If you’re trying to record clean voice audio inside your motorcycle helmet, you’ve probably discovered just how tricky it can be. Wind noise and your breathing can all sabotage an otherwise great ride video. Here are some quick tips to get the best out of your helmet mic setup:
1. Mic Positioning Is Everything
Where you place the microphone matters more than you think. Lower in the helmet, closer to the chin vent, you'll pick up a heap of wind noise—especially at higher speeds. Instead, place the mic further up where it’s more sheltered and produces cleaner audio.
2. Avoid the Direct Line of Fire
Avoid mounting the mic directly in front of your mouth. I may seem like the obvious place, but you’ll capture every “P” pop and Darth Vader breath. Slightly to the side or up towards the padding avoids this and still picks up your voice.
3. Know When to Speak
Above 80–100 km/h, wind noise becomes your enemy, no matter how fancy your setup. Even with a good microphone and optimal placement, physics ultimately prevails. So, save your commentary for slower sections—cruising through towns or scenic twisties is the sweet spot for audio clarity.
4. Low-Tech Fix: Duct Tape
It’s not glamorous, but a little duct tape over vents near the mic or around the mic capsule itself can help reduce direct wind impact. If your helmet is a little on the loud side, add some additional foam.
Final Tip: Every helmet is different, so take the time to test and adjust your setup. A little trial and error goes a long way, just like adventure riding.

For those of us who put their mics in the wrong position, have you considered a refurbishment/relocation kit? Dead cat or foam replacement?
