After inserting an external microphone, the audio performance of the AKASO action camera will be significantly improved, adding more fun and professionalism to your recording and shooting experience. Here are the advantages of using an external microphone:

1. High-quality audio: External microphones usually have better recording capabilities, accurately capturing the sound details of the surrounding environment, making your video content more vivid and realistic.

2. Noise reduction: The built-in microphone of the AKASO action camera is often affected by environmental noise, resulting in unclear sound during recording. However, an external microphone can better suppress background noise, making your recordings cleaner and purer.

3. Expanded recording range: An external microphone can also provide a larger recording range, allowing you to capture a wider range of sound scenes. Whether it's outdoor sports, natural scenery, or social activities, an external microphone can help you record more precious audio moments.

4. Professional-level recording: For users who have higher requirements for audio quality, inserting an external microphone will provide more professional recording options. You can choose different types of microphones, such as stereo microphones, directional microphones, etc., to meet the recording needs in different scenarios.

In summary, inserting an external microphone can significantly improve the audio quality of the AKASO action camera, making your video works more vivid and realistic, and providing a more professional audio effect for your experience.
