The Bose QuietComfort Ultra Earbuds are premium noise-cancelling wireless earbuds engineered for listeners who demand top-tier sound and world-leading ANC performance. Equipped with Bose’s proprietary CustomTune technology, these earbuds automatically analyze your ear canal and tailor the audio and noise cancellation to create a truly personalized listening experience.
Active noise cancellation is one of the strongest in the industry, effectively blocking out office chatter, traffic, airplane drones, and other environmental sounds. Immersive Audio with spatial processing delivers a wider, more three-dimensional soundstage, enhancing movies, gaming, and music with a more realistic sense of space.
The earbuds use high-fidelity dynamic drivers for rich bass, balanced mids, and crystal-clear highs. Three listening modes—Quiet, Aware, and Immersion—allow users to switch between full noise cancellation, transparency mode, and spatial audio enhancements.
Comfort is a major highlight thanks to Bose’s soft umbrella-style eartips and stability bands, which provide a secure fit without causing pressure even during long listening sessions. Touch controls are intuitive, enabling quick access to volume adjustments, playback, ANC modes, and calls.
Battery life reaches up to 6 hours per charge, with the case extending total listening time up to 24 hours (or slightly less when using Immersive Audio). The IPX4 water-resistant rating ensures durability during workouts and outdoor use.
With strong ANC, premium comfort, immersive sound, and refined build quality, the Bose QuietComfort Ultra Earbuds rank among the very best in high-end true wireless earbuds.
