User Tips
- Optimize Noise Cancellation: While the M53 offers excellent noise reduction, for the best call clarity, try to minimize loud background noises in your environment.

- Voice Assistant Access: Quickly double-click the mute button to activate your device's voice assistant for hands-free commands.
