In short

Get the QuietComfort Ultra Headphones (2nd Gen) if you want Bose's flagship noise cancelling in a pair that folds into its case and runs up to 30 hours. That's six hours more than the 2023 model, and this generation adds Cinema Mode, Bluetooth 5.4 and lossless audio over USB-C. They launched at $449, against $349 for Bose's QuietComfort Headphones. Skip them for workouts: Bose gives them no IP rating.

Who it is for

  • Frequent travelers. Bose rates them for up to 30 hours with noise cancelling on, and the cups fold into the carrying case.
  • Android users with a Snapdragon Sound-certified phone, which unlocks aptX Adaptive. Google Fast Pair also works on Android.
  • People who switch between a laptop and a phone all day: multipoint keeps two source devices connected at once.
  • Owners of the 2023 QuietComfort Ultra Headphones who keep running out of battery. The 2nd Gen goes from 24 hours to 30, or from 18 to 23 with Immersive Audio on.

Who should skip it

  • Anyone who wants headphones for the gym or the rain. Bose gives them no IP rating and says to avoid situations where they could get wet.
  • iPhone owners who want Apple's spatial audio and a Digital Crown. Those come with AirPods Max 2.
  • Buyers who want Bose noise cancelling for less. The non-Ultra QuietComfort Headphones launched at $349.
  • Happy owners of the 2023 Ultra. CustomTune and Immersive Audio are already yours; the 2nd Gen adds six hours of battery, Cinema Mode and USB-C lossless.

What sets it apart

  • Adjustable, adaptive noise cancelling with an updated algorithm, plus CustomTune, which fits the sound to your ears every time you put them on.
  • Up to 30 hours with noise cancelling on and 45 with it off. The 2023 Ultra is rated for 24.
  • Lossless audio over USB-C, new on this generation: 16-bit at 44.1 or 48 kHz from a compatible source, with a low-latency path Bose pitches for gaming on a computer or phone.
  • Cinema Mode, also new, widens the soundstage and brings dialogue forward; Bose suggests it for podcasts and audiobooks too.
  • Bluetooth 5.4 multipoint for two devices at once, with aptX Adaptive alongside SBC and AAC.

Caveats

  • Immersive Audio costs seven hours of battery: the rating drops from 30 hours to 23 with it on.
  • USB-C lossless means 16-bit at 44.1 or 48 kHz: CD-quality territory, not high-resolution audio.

What the 2nd Gen adds

Bose kept what defined the first QuietComfort Ultra Headphones in 2023, CustomTune and Immersive Audio, and spent this generation on battery life, a new listening mode and better wired options.

SpecUltra (2nd Gen)Ultra (2023)
Battery, Immersive Audio offUp to 30 hoursUp to 24 hours
Battery, Immersive Audio onUp to 23 hoursUp to 18 hours
Cinema ModeYesNo
Lossless audio over USB-CYesNo
CustomTuneYesYes

For most people the six extra hours are the upgrade that counts. Cinema Mode and USB-C lossless matter if you watch a lot of video or do most of your listening at a computer. Bose QuietComfort Ultra Headphones (2nd Gen) vs 1st Gen goes through both generations.

Noise cancelling, Aware Mode and Cinema Mode

Bose calls the noise cancelling adjustable and adaptive, with an updated algorithm this generation. You can set the level yourself or switch it off in the Bose app. In Aware Mode, which lets outside sound through, ActiveSense adjusts more smoothly when noise spikes suddenly, Bose says.

Immersive Audio is Bose’s spatial audio mode. Cinema Mode, new this generation, is the one to reach for with films and spoken word, since it widens the stage and pushes dialogue forward.

Bose doesn’t publish driver size, frequency response or impedance, so there’s nothing on paper to set against other flagships. You’re buying Bose’s tuning.

Battery and charging

ModeUltra (2nd Gen)
Noise cancelling on, Immersive Audio offUp to 30 hours
Immersive Audio onUp to 23 hours
Noise cancelling offUp to 45 hours
Full chargeUp to 3 hours
15-minute chargeUp to 3 hours of playback (2 with Immersive Audio)

At 30 hours with noise cancelling on, they get you through a long-haul trip without reaching for the cable, and switching noise cancelling off stretches that to 45. Charging is over USB-C, and a 15-minute top-up before you leave covers a commute or two.

Phones, codecs and multipoint

Every Bluetooth phone gets SBC or AAC. Phones certified for Snapdragon Sound also get aptX Adaptive (Bose’s UK page lists Snapdragon Sound by name), and Google Fast Pair handles pairing on Android.

Bluetooth 5.4 multipoint keeps two source devices connected at once, such as a phone and a laptop. Bose quotes a range of 30 feet (9 meters) and lists the A2DP, HFP and AVRCP profiles plus Bluetooth Low Energy.

Listening over a cable

You have two wired options. The audio cable in the box covers analog sources, and USB-C carries lossless digital audio at 16-bit and 44.1 or 48 kHz from a compatible source. Bose also pitches the USB-C connection’s low latency for gaming on a computer or a phone.

Fit, weight and folding

The cups sit around your ears on an adjustable headband, with removable protein-leather cushions on a plastic and aluminum frame. Bose gives the weight in pounds: 0.583 lb for the headphones, which works out to about 265 grams, and 1.061 lb for the entire product system. The headphones measure 1.772 × 6.299 × 8.071 inches, and the boxed system 2.185 × 6.122 × 8.406 inches.

They fold into the carrying case, and laying them flat or folding them sends them into a low-power standby that Bose says lasts for months.

Which one to buy

Frequently asked questions

What's new compared with the 2023 QuietComfort Ultra Headphones?

More battery, Cinema Mode, Bluetooth 5.4 and lossless audio over USB-C. Bose rates the 2nd Gen for 30 hours with Immersive Audio off and 23 with it on, against 24 and 18 for the 2023 pair, and adds a 45-hour rating with noise cancelling off. CustomTune and Immersive Audio carry over.

How do I tell the 2nd Gen from the 2023 model on a listing?

Look for “2nd Gen” in the name or Bose's QCUH2 model family; the full retail code is QCUH2-HEADPHONEARN. A listing that quotes 30 hours and Cinema Mode is the newer pair, since the 2023 one is rated for 24 hours.

Do they work with an iPhone?

Yes. Any Bluetooth phone pairs and connects over SBC or AAC. The two extras that lean Android are aptX Adaptive, which needs a Snapdragon Sound-certified source, and Google Fast Pair.

Do they support LDAC?

No. Bose lists SBC, AAC and aptX Adaptive, and its UK page adds Snapdragon Sound.

Can I listen over a cable?

Yes, two ways. An audio cable comes in the box, and USB-C carries lossless audio at 16-bit and 44.1 or 48 kHz from a compatible source, with low latency for games.

Do I need to press a power button?

No. On-head detection starts them up and connects to your paired devices when you put them on, and laying them flat or folding them into the case sends them into a low-power standby.

Can I wear them while they charge?

Yes, though charging is slower that way. A full charge over USB-C takes up to 3 hours, and 15 minutes buys up to 3 hours of playback, or 2 with Immersive Audio.
