The Bose QuietComfort Ultra Headphones 2nd Gen update the 2023 original rather than reinvent it. Bose extended battery life to up to 30 hours, added the ability to listen and charge at the same time over USB-C, and enabled digital audio through that same port. Bluetooth moves to version 5.4 with Snapdragon Sound support, and a new Cinema mode joins the Immersive Audio settings for films and shows.

Who the Bose QuietComfort Ultra Headphones (2nd Gen) is for

These are aimed at people who wear headphones for hours at a stretch, such as frequent flyers, train commuters and remote workers. Bose’s soft cushions and light clamping are the main appeal. The USB-C audio input is useful for laptop users who want a wired connection without a dongle. Buyers who want a hi-res Bluetooth codec on an iPhone should know that aptX Adaptive needs a compatible Android source.

What to check before buying a new Bose QuietComfort Ultra Headphones (2nd Gen) on eBay

Confirm the listing says 2nd Gen; the first-generation QuietComfort Ultra Headphones look nearly identical and are a different product.
Request a sealed box and check the case, USB-C cable and audio cable are listed in the contents.
Ask whether the item was bought from an authorised dealer so the Bose limited warranty applies in the US or Canada.
Check the colour in the photos against the title, as limited editions are also sold.
Review the return policy before buying, in case the fit does not suit you.
