Every listen deserves the premium, personalized audio, world-class noise cancellation, and entirely seamless experience of Bose QuietComfort Ultra Earbuds (2nd Gen). Feel all the feels with each song you play as CustomTune technology adapts the noise cancellation and audio performance to the shape of your ears. Because all you want is music, there’s the best Bose in-ear noise cancellation. Now it’s even smarter thanks to ActiveSense technology. In Aware Mode, it automatically smooths spikes in unwanted sounds. And Bose Immersive Audio spatializes what you hear, so it’s like listening from the acoustic sweet spot. Nine combinations of eartips and stability bands give you a fit that won’t quit, while up to 6 hours of battery life (up to 4 hours with Immersive Audio)* keep your favorites playing. The included case charges wirelessly and holds up to three additional full charges (wireless charger sold separately). Calls count, too, so AI-based background noise suppression filters out your surroundings and mics focus only on the sound of your voice for the clearest conversations. Available in Black, White Smoke, or limited-edition Deep Plum.
