The QuietComfort Ultra headphones (2nd gen) have been engineered with the utmost precision – featuring Bose’s best-ever noise-cancelling technology for headphones and excellent spatial sound for an immersive listening experience. Every note sounds bigger, every beat more powerful, every melody more immersive. Bose 360-degree sound projects your music out of your head and straight into the room – for a particularly natural listening experience. CustomTune technology personalises your sound experience by analysing the shape of your ear and adjusting the sound so that everything sounds exactly as it should. With up to 30 hours’ battery life (up to 23 hours with 360-degree sound enabled)* and exceptional comfort thanks to high-quality materials, these headphones invite you to immerse yourself in your favourite music. The ear cups nestle gently against your ears, whilst the headband distributes pressure evenly – elegant, polished metal arms add a stylish finish. Thanks to state-of-the-art Bluetooth Core 5.4 technology, you can connect your products with ease – and the Bose app lets you keep track of your paired products at all times.
