Since its release in 2017, Bose’s QuietComfort 35 II has been regarded as one of the best noise-cancelling headphones on the market. If you’re in the market for a new set of headphones, Bose’s new Quiet Comfort 45 promises better battery life and a new ambient mode.
Expect identical aesthetics and fit as the QuietComfort 35 II, albeit Bose has removed the “pleats and puckers” from the ear cushions to avoid a wrinkled appearance.

The integrated noise cancelling system has been updated in the Quiet Comfort 45. The noise-cancelling High and Low modes of the 35 II have been replaced by a “Quiet” mode that silences the ambient noise around you once turned on, and an Aware mode that beams in ambient noise—useful for when you want to converse to a friend without taking off your headphones.
“Without ever taking them off,” the business claims, “the QC45 headphones transition to complete transparency, where everything is heard again—just as naturally, clearly, and swiftly.”

Bose also improved the headphones to make them more suitable for today’s work-from-home environment. The QuietComfort 45 can “share” noise cancellation with individuals you’re talking to on a voice or video conversation by isolating the speaker’s voice while blocking out ambient noise like a coffee grinder or a barking dog.

“This means that friends, family, coworkers, and personal assistants can hear what’s being said,” Bose explains, “paving the way for more productive Zoom meetings [and] happier video conversations.”

The battery life has also been improved. The QuietComfort 45 has a 24-hour running time, which is four hours longer than the 35 II. A USB-C port is now available for charging the headphones. It will take 2.5 hours to restore them to full battery life. In the meantime, a 15-minute charge will provide you around three hours of playback time.
Pre-orders for the QuietComfort 45 begin today, with a release date of September 23. They’ll set you back $329, up from $299 for the QuietComfort 35 II. Keep an eye out for our review.
