Bose Announces QuietComfort 45 Noise-Canceling Headphones

After months of leaks and reports, Bose has finally unveiled the QuietComfort 45 headphones.

The company says that Bose QuietComfort 45 will replace the successful QuietComfort 35 II headphones and comes with an improved noise cancellation feature.

Bose has also introduced a new Aware mode with the Bose QuietComfort 45, which lets users hear what is happening in their surroundings without taking off the headphones.

Available in black or “smoke white,” they look quite similar to their QC35 II predecessors, with a design that’s much more plasticky than Bose’s other premium headphones, the Noise Canceling Headphones 700.


But that means, like before, these can be folded up for easy storage in a bag or the included carrying case. Bose says it has refined the design in subtle ways: according to the company, “pleats and puckers have been removed from soft materials, and gaps between components have been replaced with smooth transitions.”

The QuietComfort 45 headphones can be preordered now for $329.95 (₹ 24,000 approximately) and will be available from September 23. As of now, there is no confirmation about the product coming to India.

Bose is making a big deal about this product release, claiming that it’s “updating the headphone that redefined headphones.” Preorders begin today.

There are two special modes for listening to music on this headphone, the Aware mode, which we mentioned adobe and the Quiet mode. As per Bose, “In Quiet Mode, microphones inside and outside the ear cups combine with a proprietary digital chip to sense, measure, and respond to more unwanted sounds in mid-range frequencies — those typically found in commuter trains, busy office spaces, and cafés.”

The microUSB port has been replaced by a USB Type-C port. However, Bose still continues to offer a 2.5mm audio jack instead of the more universal 3.5 mm jack. Moreover, there is no 2.5mm cable in the box and you have to purchase one separately. You can adjust the audio settings and equalizer using the Bose Music app on Android and iOS.

Connectivity-wise, the headphones feature a Bluetooth 5.1 chip. The QC 45 can last up to 24 hours of battery life on a single charge. The headphones can be charged in 2.5 hours.


As per the company, the headphones should last for 24 hours on a single charge and with a 15-minutes charge, can give you three hours of battery life.

The left ear cup of the headphone comes with a single button for switching in between Quiet and Aware modes, while the right ear cup has the volume buttons and the power button along with the Bluetooth pairing slider.

The QC45s also step up in terms of microphone performance. Bose has included a beam form array for improved voice isolation on calls, and there’s also “a rejection array” that is meant to prevent distracting nearby sounds from being picked up and coming through to whoever you’re speaking with.

Like their predecessors and the NCH700 (which remain for sale), the QuietComfort 45 headphones support multipoint pairing for two connections at once.

The QC35 IIs will be discontinued and replaced by the QC45s, but you might still be able to find Bose’s older pair until existing inventory at retailers is depleted.
