The QuietComfort Ultra earbuds makes use of Bose’s noise cancellation functionality. You’re able to turn off the world around you so you can focus in on only what you want to hear. The earbuds make use of ActiveSense technology which can smooth out any spikes in sound to better combat the unwanted sounds from your surroundings. You could be sat at your desk in a crowded office surrounded by chatty co-workers or on a plane that’s taking off with the roar of the turbine running right outside your window. In either case, those distracting background noises can be muted to near silence so only your music, audiobook, or podcast comes through to your ears.

In cases where you do need to hear the outside world once more, you can flip over to Aware Mode. This will play the sounds from your environment through the earbuds so you can stay aware of what’s going on around you as you continue listening to your soundtrack without having to take out the earbuds.

Truly Immersive Audio

Bose takes the immersion even further with a mode call Immersive Audio. This is designed to give you a fully 3D experience with the sound coming through your earbuds. You’ll feel like you’re moving around in the middle of the recording studio with the different layers and instruments of the track coming from different directions, and reacting to the movement of your head.
