The new QC Ultra Headphones look almost exactly like the original version, except for some added shine.
Bose took a different approach with its new products in 2025. Instead of entirely redesigning its QuietComfort Ultra lineup, the company unveiled upgraded second-generation models of the flagship-level earbuds and headphones. Like the QuietComfort Ultra Earbuds that debuted earlier this year, the new Quiet Comfort Ultra headphones ($449) don’t offer a comprehensive overhaul. However, the changes provide enough performance improvements to further cement these as the best noise-canceling headphones that you can buy right now. Trust me, we’re much better off with this revamped version than we would be with a year (or longer) wait for something brand new with the 2023 model.
What’s new on the QuietComfort Ultra Headphones?
Bose debuted a few new features on the second-gen QuietComfort Ultra Earbuds in August that it carried over to these new headphones. First, the company improved its already stellar active noise cancelation (ANC) with tweaks to its ActiveSense technology. Specifically, the system can respond to sudden spikes in environmental noise by adapting more precisely. It’s not something you’ll notice all the time, but when you need it, you’ll be glad it's there. Otherwise, the excellent ANC performance here is just as effective as it was on the previous model. More on that in a bit.
The immersive Cinema Mode that Bose added to the QC Ultra Earbuds is also available on these headphones. It’s a sound profile that enhances dialogue clarity while keeping the rest of the soundstage as wide and enveloping as possible. I like it best for movies and TV, as the name suggests, but per Bose’s suggestion I also tried it with podcasts and audiobooks. Cinema Mode is probably overkill for those types of content, unless you’re listening to shows or titles with lots of background effects.

One of the biggest changes on the second-gen QC Ultra Headphones is how Bose decided to handle power management. Most importantly, the company extended battery life in all use cases. With ANC on (and Immersive Audio off), you’ll get up to 30 hours of listening time. Turn off ANC and that jumps to 45 hours. When you decide to enable both ANC and Bose’s spatial Immersive Audio, you can expect up to 23 hours on a charge. Compared to those on the first-generation model, all of these numbers are up by at least five hours, which is a significant boost.

Like the previous QC Ultra Headphones, this model has an automatic disconnection feature after 10 minutes of standby . But the company went a step further on this version by adding a low-power mode that the headphones enter after 30 minutes of idle time. And if you want to disconnect them quickly, you can rotate the earcups and lay them on a flat surface. That’ll make them go into a deeper standby mode that Bose says can run “for months.” All of this means you can effectively turn the new QuietComfort Ultra Headphones on and off by putting them on and taking them off. If you’re using them regularly, you’ll never have to press the power button.
Sound-wise, the big upgrade on these headphones is the addition of lossless audio over USB-C. Like the AirPods Max, this model can be connected with a cable to your phone, tablet, laptop or desktop to stream or play higher-quality tunes from compatible services or your library. Bose says you can expect 16-bit 44.1kHz or 48kHz audio depending on your source. It’s yet another nice-to-have feature that’s becoming standard fare on premium wireless headphones.
