Bose QuietComfort Ultra Wireless Noise Cancelling Earbuds Renewed

The Bose QuietComfort Ultra Earbuds represent Bose's most advanced true wireless noise cancelling earbuds, combining world-class active noise cancellation with proprietary spatial audio technology. At the heart of the experience is Bose Immersive Audio, which processes sound to create a spacious, three-dimensional soundstage that places music and audio around the listener rather than pinning it between the ears. This is complemented by CustomTune, a personalization system that plays a brief calibration tone each time the earbuds are inserted, analyzing the acoustic properties of each ear canal to optimize both sound reproduction and noise cancellation for the individual user. The result is a listening experience that adapts to you rather than delivering a one-size-fits-all profile.

Three listening modes offer flexible control over your audio environment. Quiet Mode engages full active noise cancellation to block ambient sound for focused listening. Aware Mode uses the built-in microphones to pass through external sound transparently, allowing conversation and environmental awareness without removing the earbuds. Immersion Mode layers spatial audio on top of full noise cancellation for the deepest listening experience. Connectivity is handled via Bluetooth 5.3, and the earbuds feature noise-rejecting microphones for clear voice calls. The fit system includes nine combinations of silicone eartips and stability bands, ensuring a secure seal that is essential for both comfort and noise isolation performance. Battery life reaches up to 6 hours in standard mode, with a quick-charge feature that delivers roughly 2 hours of playback from just 20 minutes of charging.
