What does it mean when AI noise reduction “keeps only the voice”?

The built-in AI noise-reduction chip analyzes the sound picked up by the microphone in real time. It identifies and suppresses the following types of noise while preserving clear speech. Even in a very loud environment, the other party primarily hears the speaker’s voice rather than the background.

• Music from a venue or stage sound system.
• Sudden sounds such as knocks, horns, and impacts.
• Outdoor wind noise.
