3.2. Sound Modes (Active Noise Cancellation, Transparency, Normal)
The XT300 earbuds offer three distinct sound modes:
- Active Noise Cancellation (ANC): Long-press the Multi-Function Button (MFB) on the left earbud for 3 seconds to activate. This mode significantly reduces ambient noise, allowing you to focus on your audio.
- Transparency Mode: Cycle through modes by long-pressing the MFB. This mode allows you to hear your surroundings clearly while still enjoying your audio, maintaining awareness of your environment.
- Normal Mode: Cycle through modes by long-pressing the MFB. This mode provides standard audio without active noise cancellation or transparency features. The earbuds can intelligently switch to Environmental Noise Cancellation (ENC) during phone calls to ensure clear communication.
