Best External Microphones for Action Cameras in 2024

You’ve just captured an epic mountain bike descent—wind roaring, tires crunching on gravel, your heart pounding. You hit record on your action camera, and the footage looks incredible. But when you play it back? The audio is muffled, distant, or drowned out by wind noise. Sound familiar?

If you’ve ever been frustrated by poor audio quality in your action camera videos, you’re not alone. Most built-in microphones on action cameras like GoPro, DJI Osmo Action, or Insta360 are designed for compactness, not sound clarity. They’re fine for casual clips, but if you’re serious about vlogging, travel content, or documenting adventures, you need better audio. That’s where external microphones for action cameras come in.

In 2024, the market is packed with options—clip-on mics, lavalier mics, shotgun mics, and even wireless systems—all designed to plug into or connect with your action camera. Whether you’re a weekend warrior, a travel creator, or a professional filmmaker, upgrading your audio can transform your content. In this guide, we’ll walk you through everything you need to know about choosing the best external microphone for your action camera, including top picks, key features, and real-world tips to get the clearest sound possible.

Why Your Action Camera Needs an External Microphone

Let’s be honest: most action cameras prioritize image quality over sound. The built-in mics are often tiny, placed in hard-to-reach spots, and easily blocked by housing or wind. Even with wind noise reduction software, they struggle to capture clear voice or ambient sound. That’s a problem if you’re trying to tell a story, narrate your journey, or capture the roar of a waterfall up close.

The Limitations of Built-In Mics

Built-in microphones on action cameras are typically omnidirectional, meaning they pick up sound from all directions. While that sounds good in theory, it means they also capture unwanted noise—like wind, engine hum, or crowd chatter. Plus, they’re often recessed into the camera body, which muffles audio further. If you’ve ever watched a GoPro video where your voice sounds like you’re talking from inside a tin can, that’s why.

How External Mics Solve the Problem

External microphones for action cameras are designed with specific use cases in mind. They offer better directionality, improved frequency response, and often include wind protection. Whether you’re skiing down a slope, filming a scuba dive, or interviewing a local guide during a trek, an external mic can dramatically improve clarity and immersion.

For example, a directional shotgun mic focuses on sound in front of the camera, reducing background noise. A lavalier mic clips to your shirt and captures your voice directly, ideal for talking-head style vlogs. And wireless systems let you move freely without worrying about cables getting snagged.

Real-World Impact on Your Content

Imagine two versions of the same video: one with built-in audio, and one with an external mic. In the first, your voice is faint, wind howls, and the sound of your kayak paddling is barely audible. In the second, your narration is crisp, the water lapping against the hull is clear, and the wind is manageable. Viewers will stay engaged longer, understand your story better, and be more likely to share or subscribe.

Good audio isn’t just a nice-to-have—it’s essential for professional-quality content. In fact, studies show that poor audio is one of the top reasons viewers abandon videos, even if the visuals are stunning. Investing in an external microphone for your action camera is one of the smartest upgrades you can make in 2024.

Types of External Microphones for Action Cameras

Not all external microphones are created equal. The right choice depends on your filming style, environment, and budget. Here’s a breakdown of the most common types of external microphones for action cameras, along with their pros and cons.

Shotgun Microphones

Shotgun mics are long, cylindrical microphones designed to capture sound from a specific direction—usually straight ahead. They’re highly directional, which makes them great for isolating voices or ambient sounds while minimizing background noise.

Best for: Outdoor filming, interviews, travel vlogging, and situations where you want to focus on a specific sound source.

How to Choose the Right External Microphone for Your Needs

With so many options, how do you pick the right external microphone for your action camera? It comes down to your filming style, environment, and priorities. Here’s a practical guide to help you decide.

Consider Your Filming Environment

Are you mostly filming outdoors in windy conditions? A shotgun mic with a good windshield is essential. If you’re indoors or in quiet settings, a lavalier mic might be sufficient. For underwater adventures, you’ll need a hydrophone or a waterproof housing with mic support.

Tip: Always test your mic in the environment you’ll be filming in. Wind, water, and crowds can drastically affect audio quality.

Match the Mic to Your Camera’s Input

Not all action cameras support external microphones. Check your camera’s specs:

• GoPro Hero 9 and newer: Supports external mics via USB-C or 3.5mm (with adapter)
• DJI Osmo Action 3/4: 3.5mm mic input
• Insta360 ONE RS/X3: Supports external audio via Audio Adapter
• Older models: May require firmware updates or adapters

Tip: If your camera lacks a mic input, look for wireless systems that connect via USB-C or use Bluetooth (if supported).

Think About Mobility and Convenience

Are you skiing, surfing, or hiking? A wireless mic gives you freedom to move. But if you’re mounting your camera to a helmet or handlebar, a wired shotgun mic might be more practical.

Tip: Use a shock mount to reduce handling noise, and secure cables with tape or clips to prevent snags.

Set a Realistic Budget

External microphones range from $30 to $300+. While premium models offer better sound and features, you don’t need to break the bank for a noticeable improvement.

Budget-friendly options: Takstar SGC-598, Boya BY-M1

Mid-range: Rode VideoMicro, DJI Mic 2

High-end: Sennheiser MKE 440, Sony ECM-W2BT

Tip: Start with a mid-range mic and upgrade later. Many creators begin with a wired shotgun mic and move to wireless as their needs grow.

Tips for Getting the Best Audio Quality

Even the best microphone won’t save your audio if it’s not used properly. Here are some practical tips to maximize sound quality when using external microphones for action cameras.

Use a Windshield or Deadcat

Wind noise is the enemy of clear audio. Always use a foam windshield (for light wind) or a furry “deadcat” (for strong wind). Most external mics come with one, but you can buy aftermarket versions for better protection.

Example: The Rode WS6 deadcat reduces wind noise by up to 30dB—essential for mountain biking or skiing.

Position the Mic Correctly

For lavalier mics, clip it 6–8 inches below your chin, slightly off-center to avoid plosives (“p” and “b” sounds). For shotgun mics, point it toward the sound source and keep it as close as possible without entering the frame.

Tip: Use a boom pole or extension cable to position the mic closer to the subject.

Monitor Your Audio

If your camera or wireless system supports it, use headphones to monitor audio in real time. This helps you catch issues like distortion, low volume, or interference before you finish filming.

Tip: Some wireless systems, like the DJI Mic 2, include a headphone jack on the receiver for monitoring.

Record in a Quiet Environment When Possible

Even the best mic can’t fully eliminate background noise. When recording voiceovers or interviews, choose quiet locations or use natural barriers (like trees or buildings) to block wind and traffic.

Edit and Enhance in Post

Use editing software like Adobe Premiere Pro, DaVinci Resolve, or even free tools like Audacity to clean up audio. Apply noise reduction, equalization, and compression to make your voice stand out.

Tip: Record a few seconds of ambient noise (“room tone”) to use as a noise profile for reduction tools.

Compatibility and Setup Guide

Getting your external microphone to work with your action camera doesn’t have to be complicated. Here’s a quick compatibility and setup guide for popular models.

GoPro Hero 9/10/11/12

These models support external mics via USB-C or 3.5mm (with the Pro Mic Adapter). Simply plug in your mic, enable external audio in settings, and you’re ready to go.

Setup steps:

1. Connect the mic to the adapter or USB-C port
2. Go to Settings > Audio > Microphone > External
3. Test the audio and adjust levels if needed

DJI Osmo Action 3/4

These cameras have a 3.5mm mic input on the side. Plug in your mic, and the camera will automatically detect it.

Use the Audio Adapter (sold separately) to connect external mics. The adapter plugs into the USB-C port and provides a 3.5mm input.

Note: Not all third-party mics are fully compatible—check Insta360’s compatibility list.

Wireless Systems

For wireless mics like the DJI Mic 2 or Rode Wireless GO II, pair the transmitter and receiver, then connect the receiver to your camera. Most systems auto-pair, but consult the manual for first-time setup.

Tip: Keep transmitters charged and within range (usually 100–300 feet) to avoid dropouts.

Final Thoughts: Is an External Microphone Worth It?

Absolutely. If you’re serious about creating engaging, professional-quality content with your action camera, an external microphone is one of the best investments you can make. While built-in mics have improved over the years, they still can’t match the clarity, directionality, and noise control of a dedicated external mic.
