A:Answer The Bose QuietComfort Headphones are not the QuietComfort 45 themselves, but rather the successors to the QuietComfort 45 Headphones. They carry forward the same comfortable design and legendary noise cancellation but add refinements like customizable listening modes beyond just Quiet and Aware. Audio performance has also been enhanced, delivering richer, high‑fidelity sound. With up to 24 hours of battery life and the option to use an audio cable with an in‑line mic, they’re designed to fit seamlessly into travel, office, or home use. Overall, the QuietComfort Headphones take what the QuietComfort 45 offered and elevate it with added features and more versatility.
