Bose overhauls the QuietComfort Ultra Headphones with lossless audio and longer battery life

Bose announced a refresh of its QuietComfort Ultra Earbuds over the summer and now it's back with an overhaul of its flagship noise-canceling headphones. The company has employed the second-generation moniker once again on the new QuietComfort Ultra Headphones, but this time the list of updates is a bit more substantial. Bose says it made tweaks to audio performance, active noise cancellation (ANC), battery life, power efficiency and more. Surprisingly, the company managed to make its upgrades without raising the price. 

The biggest changes for the QC Ultra Headphones come in the sound department. First, lossless audio is now available over wired USB-C connection. Bose says you can expect 16-bit/44.1kHz or 48kHz playback and the setup doubles as a low-latency option for desktop or mobile gaming. When it comes to Immersive Audio — Bose's take on spatial audio that doesn't require specialized content — the company has added a new Cinema mode. 

By "spatializing and balancing background sound with other audio effects," Bose says it creates a "movie-like experience" thanks to a wider soundstage that's placed in front of the listener. As a result, dialogue clarity is enhanced, which makes Cinema mode an option for podcasts and audiobooks in addition to movies and TV shows. For general listening, the company provides deeper bass at high volume, more natural sounding treble and consistent clarity even when the content is loud. It also reduced the sound created by the ANC tech so that it's less apparent in quieter environments.

Speaking of ANC, Bose made the same update here that it did on the QC Ultra Earbuds. In Aware or transparency mode, the headphones better handle sudden changes in environmental noise (like sirens) with smoother changes to noise-canceling levels. On the QC Ultra Headphones, you can now disable ANC completely or manually adjust it to suit your needs. 

Bose extended the battery life to 30 hours of ANC use or up to 45 hours with noise cancellation disabled. If you opt for that spatial Immersive Audio all the time, you can expect up to 24 hours of use now. If you run out of juice before you want to take a break, the QC Ultra Headphones can be charged during use via the USB-C port. To help you conserve battery power, the headphones will now enter a standby mode when you lay them flat or fold them into their case. And when the time comes to resume listening, improved wear detection automatically turns on the headphones when they're placed on your head. 

Lastly, you'll notice that Bose opted for polished metal on the headband where the yokes used to have a flat finish. There are also two new colors: Driftwood Sand (tan) and Midnight Violet (purple). 

The second-gen QuietComfort Ultra Headphones are available for preorder today from Bose in black, white, tan and violet color options. The price remains $449, same as the original version, and general availability is scheduled for October 2.
