QuietComfort Headphones are the successors to QuietComfort 45, offering high-fidelity audio and world-class noise cancellation. Ultra Headphones are Bose’s most premium with advanced tech and features.

A proprietary design that uses external ports to enlarge the acoustic volume, improving sound and active noise reduction in a smaller, lighter headphone.

It uses both active and passive noise reduction, with microphones inside and outside the earcups to sense and cancel ambient sound, and earcup fit/design for passive isolation.

Aware Mode uses external mics to let ambient sounds be heard while still enjoying audio, so you can stay aware of surroundings like traffic or announcements.

Designed for long sessions with lightweight materials, protein-leather cushions, rotating earcups, and minimal clamping force for extended comfort.
