Unfortunately, the provided references do not explain how audio "beats" work. They describe the controls for Beats headphones. The references explain how to use the buttons on the left ear cup of Beats headphones:
- Use the "b" button to play/pause audio or answer/decline calls.
- Use the volume buttons (above and below the "b" button) to control volume.
- Press and hold the "b" button to activate Siri (or say "Hey Siri").
Therefore, I cannot explain how audio beats work based on the given information.
