In-ear TWS · ANC · 6.5h/24h · aptX Adaptive · BT 5.3

The Bose QuietComfort Ultra Earbuds 2nd Generation is Bose's flagship true wireless earbud, engineered to deliver the company's best-in-class noise cancellation in an in-ear form factor. The 9.3mm drivers paired with the enhanced CustomTune system create a personalized sound profile that adapts to your unique ear anatomy for optimal ANC and audio performance. Its standout feature is the class-leading noise cancellation that rivals the AirPods Pro 3 as the best ANC in any earbud, complemented by Bose's Immersive Audio spatial sound technology. These earbuds are perfect for commuters, frequent flyers, and open-office workers who demand maximum silence from their earbuds. Compared to the AirPods Pro 3, the Bose offers comparable ANC with aptX Adaptive codec support for Android users but lacks the health monitoring features. With 6.5 hours of earbud playback, 24 hours total from the case, and IPX4 splash resistance at 6.2 grams, they deliver Bose's signature quiet in a premium compact package.
