QuietComfort Ultra Earbuds represent the apex of the Bose QuietComfort series. Packed with the latest audio immersion technology and offering superior comfort, these earbuds are the perfect companion for any casual listener, musician, or audiophile. Bose has raised the bar with a new level of noise cancellation, offering Quiet, Aware with Active Sense, and Immersion modes to filter out your environment at convenient levels. With up to six hours of continuous battery life, you'll have more than enough power to get through the workday. Should you find yourself in a pinch, the included wireless charging case can provide up to three additional charges, equaling 18 hours of use as long as you have your case on hand. It's no secret that Bose is synonymous with superior audio performance — reap the rewards for yourself with QuietComfort Ultra Earbuds.
The character and scope of your earbuds’ output, along with the quality of your audio, significantly impact your overall listening experience. With the QuietComfort Ultra Earbuds’ enhanced driver technology and updated immersion features, Bose has successfully addressed both. Spatialization within the Bose Immersive Audio feature places your music around you, giving you an authentic stereo experience at any given moment — a huge upgrade from many contemporary static sound earphones. No matter what content you’re listening to, QuietComfort Ultra Earbuds ensure the most authentic playback possible.


Sweetwater audiophiles are particular about the subtleties of their sound. If you're the same way, you'll love the Bose Music app. Tweak your bass, midrange, and treble to taste with the onboard 3-band EQ for a superior personalized listening experience. You'll also have access to shortcuts, a simple device setup process, control over other connected devices, and much more, all within a straightforward interface.
The days of constantly swapping out your eartips are over. The Bose Fit Kit includes three pairs of eartips and stability bands, granting you nine combinations to create the perfect fit for your ear. Once you’ve found an option that works for you, put your earbuds in and press play — the Bose CustomTune technology will analyze your ear shape to create an optimal output to give you the most transparent and immersive sound possible. Sweetwater audiophiles agree there’s no easier way to achieve personalized audio than with a pair of Bose QuietComfort Ultra Earbuds.
