BOSE QUIETCOMFORT ULTRA WIRELESS NOISE CANCELLING EARBUDS
Bluetooth In-Ear Headphones with Spatial Audio and World-Class Noise Cancellation
INTRODUCTION TO BOSE QUIETCOMFORT ULTRA
The Bose QuietComfort Ultra Wireless Earbuds combine state-of-the-art noise cancellation, immersive spatial audio, and premium comfort into one compact design. These earbuds redefine portable sound by offering a professional-grade listening experience with advanced customization features. Designed for both entertainment and productivity, they seamlessly adapt to different environments while maintaining Bose’s renowned sound quality.
With Bluetooth multipoint connectivity, intuitive touch controls, and a lightweight ergonomic fit, the QuietComfort Ultra earbuds deliver unmatched versatility. Whether listening to music, attending a virtual meeting, or traveling in noisy environments, they provide a consistent, high-quality audio experience.
IMMERSIVE SPATIAL AUDIO EXPERIENCE
The standout feature of these earbuds is spatial audio with Bose Immersive Audio technology. This feature creates the impression that the sound is positioned directly in front of the listener, producing a three-dimensional soundstage. Music and media feel more natural, with precise directionality that enhances immersion.
By simulating the effect of high-end stereo speakers, spatial audio adds depth and realism to every listening session. It is particularly effective for streaming movies, playing immersive games, or enjoying high-fidelity music.
WORLD-CLASS NOISE CANCELLATION WITH CUSTOMTUNE
The QuietComfort Ultra earbuds use CustomTune technology to analyze the unique shape of each ear canal and adjust audio output accordingly. This ensures that active noise cancellation is not only powerful but also tailored to the listener.
The system continuously adapts in real time to changing environments, blocking out distractions such as traffic, airplane engines, or office chatter. This advanced customization makes the listening experience more precise and immersive than standard noise cancelling technologies.
THREE DISTINCT LISTENING MODES
To accommodate various environments, the earbuds provide three listening modes.
-
Quiet Mode delivers full noise cancellation, isolating the user completely from external distractions.
-
Aware Mode allows surrounding sounds to blend naturally with audio, ensuring safety and awareness in public spaces.
-
Immersion Mode combines full noise cancellation with spatial audio, creating the most engaging listening experience.
These modes make it simple to adjust audio performance according to the activity, whether working in silence, commuting in a city, or relaxing at home.
CUSTOMIZABLE FIT AND ALL-DAY COMFORT
Comfort is an essential factor in extended listening sessions, and Bose has designed the QuietComfort Ultra with nine interchangeable ear tips and stability bands. This ensures that users can find the ideal fit for different ear shapes and sizes.
The materials are soft and lightweight, reducing pressure inside the ear canal. The secure fit also improves passive noise isolation, complementing the active cancellation system. This ergonomic design makes the earbuds suitable for hours of continuous use without discomfort.
LONG-LASTING BATTERY PERFORMANCE
The earbuds provide up to 6 hours of listening time per charge, and up to 4 hours when Immersive Audio is activated. The included charging case extends playback significantly and features fast charging capabilities. A quick 20-minute charge provides up to 2 hours of additional playtime, ensuring reliability during travel or busy schedules.
The combination of efficient battery management and quick recharge options makes the QuietComfort Ultra ideal for both short commutes and long trips.
ADVANCED BLUETOOTH CONNECTIVITY
Featuring Bluetooth multipoint technology, the earbuds allow users to connect to two devices simultaneously. This enables seamless switching between a smartphone, laptop, or tablet without manual reconnection.
With Bluetooth 5.3, the earbuds maintain strong, low-latency connections suitable for both audio streaming and video playback. The stable wireless performance minimizes interruptions and ensures consistent sound quality across devices.
CLEAR VOICE CALLS WITH NOISE REJECTION
The QuietComfort Ultra earbuds are designed for professional-quality communication. Equipped with noise-rejecting microphones, they reduce background interference and prioritize the speaker’s voice during calls.
This makes conversations clearer even in challenging environments such as busy streets or public transportation. The result is consistent performance for virtual meetings, personal calls, and voice assistant interaction.
FLEXIBLE USAGE WITH SINGLE OR DUAL EARBUDS
Another practical feature is the ability to listen with one earbud or both. This flexibility ensures convenience in different scenarios. For example, using a single earbud allows users to stay aware of their surroundings while still accessing audio or calls.
Both earbuds deliver full sound quality independently, maintaining balance and clarity regardless of configuration.
INTUITIVE TOUCH CONTROLS
The earbuds incorporate responsive touch-sensitive surfaces for easy navigation. Users can control volume, skip tracks, answer calls, and switch listening modes with simple gestures.
This hands-free control system reduces reliance on smartphones and makes operation faster and more intuitive. The system is also customizable through the Bose Music app, allowing users to assign controls based on personal preferences.
DURABILITY AND BUILD QUALITY
Built with IPX4 water resistance, the QuietComfort Ultra earbuds are resistant to sweat and light rain. This makes them suitable for exercise and outdoor use in varying conditions.
The housing is engineered for durability while maintaining a lightweight structure. Combined with the protective charging case, the earbuds are built to withstand daily wear and travel.
BOSE MUSIC APP INTEGRATION
The Bose Music app serves as a companion tool for managing settings, updates, and customization. It allows users to:
-
Adjust noise cancellation levels.
-
Personalize touch controls.
-
Update firmware to access new features.
-
Optimize fit using ear tip and stability band guidance.
This integration ensures that the earbuds remain future-ready, receiving enhancements and improvements over time.
