World-Class Noise Cancellation
To deliver our best noise cancellation, the QC Ultra headphones use both active and passive noise reduction technologies,
employing a sophisticated approach for active noise cancellation (ANC).

CustomTune Technology
Bose's CustomTune technology elevates the listening experience
by analyzing your ears and automatically adjusting the sound and active noise cancellation to their unique shape.
By calibrating sound and noise cancellation precisely to the acoustic characteristics of each ear canal,
music reaches your eardrum with its original balance intact, resulting in better sound and stronger noise cancellation.

Comfort and Stability
The Bose Fit Kit includes nine potential combinations of eartips and stability bands to help you find the ideal fit for each ear.
Soft silicone umbrella-shaped eartips provide all-day comfort
while the stability bands comfortably and securely hug the contours of your ears.

One App. Total Control.
The Bose app maximizes everything the headphones have to offer,
ensuring optimal functionality with regular software updates and access to the latest features.
Create shortcuts: assign or change shortcuts, access your voice assistant, and more.
Create a mode: create custom modes with your chosen level of noise cancellation.
Customize the sound: adjust EQ settings by changing bass, mid-range, and treble levels to your taste.

Up to 6 Hours of Battery Life

and the case holds up to 3 additional full charges.
