Released more than 20 years ago, the original Bose QuietComfort headphones set the standard for noise-cancelling performance. The latest iteration of these iconic cans is the QuietComfort 45, which boasts 24-hour battery life, industry-leading ANC technologies, and an ambient noise feature called Aware Mode for safety & convenience while connected. Legendary Bose sound? Absolutely. And control buttons on the ear cups let you toggle easily between tracks, modes, volume & calls.
