Noise-canceling microphone detects external sound waves, and then, before you hear the external sound waves, the headset will be comparable with the anti-noise wave to cancel out, so feed the noise reduction achieved before, enabling users to reduce the sense of hearing to the external environment .

The noise-cancelling microphone detects external sound waves, and then, before you hear them, the headset offsets them with the equivalent noise-resistant waves, allowing for feed-forward noise reduction and reducing the user's ability to hear the outside environment.

The noise reduction microphone will detect the external sound waves, and then, before you hear these external sound waves, the earphone will use the equivalent anti noise sound wave to cancel them, so as to achieve feedforward noise reduction and reduce the user's sense of listening to the external environment.<br>
