The Bose QuietComfort Ultra Headphones (2nd Gen) deliver personalized, high-fidelity listening with advanced noise cancellation and spatialized audio. Designed with premium materials and cushioned ear cups, these over-ear wireless headphones provide extended comfort for long listening sessions. CustomTune adapts sound to your ears, and optional wired connection offers lossless playback. Bluetooth 5.4 enables wireless use up to 10 m, and the integrated microphone supports calls and voice interaction.

Advantages

Adaptive CustomTune technology personalizes audio to the shape of your ears for clearer detail. Multiple noise control modes include a Quiet Mode for maximal around-ear cancellation and an Aware Mode to let in environmental sound. Soft cushions and an even-distributing headband increase comfort during prolonged use. Long battery life allows up to 30 hours of playback in Quiet and Aware modes (about 23 hours with Immersive Audio), and wired listening is available for lossless, high-resolution audio. The headphones are compatible with the Bose app for step-by-step setup, EQ customization, and shortcuts.
