Operating Your Earbuds

Listening Modes

The QuietComfort Ultra Earbuds offer three distinct listening modes:

• Quiet Mode: Engages world-class active noise cancellation to minimize distractions.
• Aware Mode: Allows you to hear your surroundings while still enjoying your audio.
• Immersion Mode: Combines full noise cancellation with Bose Immersive Audio for a deeply spatialized listening experience.

Switch between modes using the intuitive touch controls on the earbuds or through the Bose app.

Spatial Audio

Experience breakthrough spatialized audio that places sound directly in front of you, making your music feel more real and immersive. Bose Immersive Audio takes this further, moving the sound out of your head and positioning it in front of you for a natural listening experience.

Calls and Microphones

The earbuds feature noise-rejecting microphones that filter out background noise, ensuring clearer calls. You can answer calls and play music through both earbuds or use a single earbud, depending on your preference.

Battery Life

Enjoy up to 6 hours of listening time on a single charge (up to 4 hours with Immersive Audio enabled). The included charging case provides up to three additional charges, extending your total listening time significantly.

Maintenance

Cleaning Your Earbuds

Regularly clean your earbuds and charging case to ensure optimal performance and hygiene. Use a soft, dry cloth to wipe down the exterior of the earbuds and case. For the eartips, remove them from the earbuds and gently clean with a damp cloth and mild soap if necessary, then allow them to air dry completely before reattaching.

Storage

When not in use, store your earbuds in their charging case to protect them from dust, debris, and potential damage. Store the case in a cool, dry place away from extreme temperatures.
