Welcome the second generation of QuietComfort Ultra earbuds, delivering personalised, high-impact sound and advanced noise cancellation. Using CustomTune technology, the audio performance is automatically tuned to the shape of your ears, while spatialised sound pulls you into the immersive world of your music, films and podcasts.

Designed for all-day comfort, these true wireless earbuds offer a secure, adjustable fit and powerful performance that adapts seamlessly to your surroundings.

Sound & Noise Cancellation

CustomTune technology analyses your ears to optimise both sound quality and noise cancellation, creating a listening experience tailored uniquely to you. The result is rich, detailed audio and exceptional noise reduction with every play.

World-class noise cancellation is further enhanced by ActiveSense technology, which automatically adapts to changes in your environment. Even in Aware Mode, sudden background noises are smoothed out to help minimise distractions.

Listening Modes

• Quiet Mode: Full noise cancellation for total immersion
• Aware Mode: Transparency to stay aware of your surroundings
• Immersion Mode: Combines noise cancelling with immersive audio for added depth

Immersive Audio

Bose Immersive Audio creates a spatial listening experience that places sound beyond the earbuds themselves. Music feels more natural and expansive, while films gain theatre-like depth and realism.

Calls & Connectivity

Noise-rejecting microphones and AI-based background noise suppression ensure clear phone calls, even in busy environments. Calls can be taken through one or both earbuds for added convenience.

Bluetooth multipoint connectivity allows seamless switching between devices, while advanced Bluetooth 5.3 maintains a strong and reliable connection.

Controls & App Integration

Touch controls on the earbuds let you play or pause music, adjust volume, change tracks, answer calls and switch modes without reaching for your phone.

The companion app allows further personalisation, including adjustable EQ settings, custom listening modes, battery status checks and device management.
