The QuietComfort Ultra Headphones feature three primary noise control modes:

• Quiet Mode: Provides world-class active noise cancellation, significantly reducing ambient sounds for an undisturbed listening experience.
• Aware Mode: Allows you to hear your surroundings while still enjoying your audio. This mode is ideal for situations where you need to be aware of your environment, such as walking in a city or listening for announcements.

Switch between modes using the button on the left earcup or through the Bose Music app.

These features are automatically enabled and enhanced via the Bose Music app.

3.3 Call Management

The integrated microphones are designed to focus on your voice and filter out background noise, providing clear phone calls. Use the multi-function button on the right earcup to:

• Answer/End calls: Single press

The headphones offer up to 24 hours of battery life with standard use, and up to 18 hours with Immersive Audio enabled.
