Operation

- Gentle Mode: For light noise reduction.
- General Mode: Standard noise reduction for everyday use.
- Ultra Mode: Maximum noise reduction for very noisy environments (e.g., airplanes, trains).
Press the ANC button on the headphone to cycle through the modes or manage them via the UGREEN App.
