Bose QuietComfort Ultra headphones make everything you can feel in the music even better. It starts with first-class noise cancelling, which suppresses even more noise than previous models. The groundbreaking spatial sound makes your music feel more immersive than ever before. Bose Immersive Audio takes what you hear out of your head and puts it in front of you so you can hear it as naturally as possible - regardless of the content or source. And CustomTune technology enhances your sound even further by analysing the shape of your ear and adjusting the audio performance so everything you hear comes through exactly as it should. Music without end - with a battery life of up to 24 hours (up to 18 hours with Immersive Audio) and unrivalled wearing comfort thanks to particularly high-quality materials. The ear cups gently enclose your ears, while the headband distributes the pressure evenly. And the slim metal arms ensure an elegant design. Connect to your devices via advanced Bluetooth 5.3 and keep track of your paired devices in the Bose Music app. Plus, setup is quick and easy, you have access to customisable EQ settings and much more.
