Obsessively engineered with Bose's best noise cancellation for headphones and spatialised audio for immersive listening, the QuietComfort Ultra Headphones (2nd Gen) make every note expand, every beat hit harder, and every melody take up more space. Sink deeper into your favourite songs and sounds with the ultimate combination of plush comfort, premium design, and seamless connectivity.

Bose Immersive Audio pushes the boundary of what it means to listen. It spatialises what you're hearing by taking it out of your head and placing it in front of you – putting you in the acoustic sweet spot.

With the new Cinema Mode, your favourite video content comes to life in a whole new way. Connect to your preferred device, and this sophisticated feature spatialises and balances background sound and sound effects – delivering a movie-like experience wherever you go.

Bose's best noise cancellation for headphones lets you do what you need to do, uninterrupted. The loud hum of an aeroplane? Annoying office chatter? TV playing in another room? Silenced.
