Image 5.1: Overview of Noise Control Modes

This image illustrates the key noise control technologies: Hybrid Active Noise Cancellation (ANC) for reducing ambient noise, Environmental Noise Cancellation (ENC) for clear calls, and Transparency Mode for hearing your surroundings.

Image 5.2: Hybrid Active Noise Cancelling Explained

This diagram shows how Hybrid ANC works using both external and internal microphones to filter out up to 95% of ambient noise, such as engine sounds.

• Hybrid Active Noise Cancelling (ANC): Press the ANC/Transparency Mode button to activate. This mode significantly reduces ambient noise, ideal for travel or noisy environments.
• Transparency Mode: Press the ANC/Transparency Mode button again to switch to Transparency Mode. This allows external sounds to pass through, enabling you to hear your surroundings without removing the headphones.
• Normal Mode (Music Mode): Press the ANC/Transparency Mode button a third time to return to normal mode, where ANC and Transparency are off. This mode provides balanced sound for a comprehensive listening experience.

5.3. Music Playback and Calls

• Next Track: Long press the Volume Up button.
• Previous Track: Long press the Volume Down button.

• Volume Down: Short press the Volume Down button.
• Answer/End Call: Short press the MFB.
• Reject Call: Long press the MFB.
