The QuietComfort Ultra 2nd Gen White Smoke is the second generation of Bose’s top over-ear headphone in its soft off-white finish, with polished silver yokes holding the ear cups. Bose announced it in September 2025 and put it on sale on 2 October 2025. This generation adds Cinema Mode for clearer dialogue in films, lossless digital audio over USB-C, a smoother ActiveSense in Aware Mode and longer battery life of up to 30 hours, while keeping CustomTune and Bose’s noise cancelling.

White Smoke up close, and who it suits
White Smoke is not a bright white. It is a muted off-white with a faint grey cast, calm under office lighting and on video calls, and the polished mirror-finish yokes look almost like jewellery against it. The QuietComfort Ultra 2nd Gen White Smoke suits people with silver or light devices such as a MacBook, and travellers in summer, since a pale finish absorbs less sun heat than black. The trade-off is care: pale protein-leather cushions pick up marks from skin and hair products sooner, so wipe them with a slightly damp cloth every couple of weeks and store the headphones in their case, away from dyed fabrics.
Cinema Mode and clearer dialogue
Films and series are mixed for rooms with speakers around you, so on two headphone drivers speech can get buried under music and effects. Cinema Mode spatialises the soundtrack, widens the stage in front of you and makes dialogue clearer, and Bose says it also helps spoken content such as podcasts and audiobooks. On the QuietComfort Ultra 2nd Gen White Smoke, Cinema Mode is separate from Immersion, which is tuned for music, so you choose the mode that fits what you are watching or hearing. On the QuietComfort Ultra 2nd Gen White Smoke that can mean switching subtitles off more often.
Quiet, Aware, Immersion and smoother ActiveSense
Quiet Mode runs full noise cancelling. Aware Mode lets your surroundings in, and ActiveSense steps in when a siren or passing train spikes the noise. Bose updated the ActiveSense algorithm in this generation so the noise cancelling level changes smoothly instead of jumping. Immersion turns on Immersive Audio with Still or Motion settings, and Cinema Mode handles video. In the Bose app you can save custom modes, adjust or switch off noise cancelling manually, use the EQ and set shortcuts. CustomTune still measures your ear at every start-up and tunes sound and noise cancelling to it.
Lossless USB-C audio and Bluetooth 5.4
Connected by USB-C cable, the QuietComfort Ultra 2nd Gen White Smoke receives lossless digital audio at 16-bit, 44.1 or 48 kHz from compatible sources, with low latency for gaming, and it charges from the same cable while you listen. Wirelessly it uses Bluetooth 5.4 with a range of up to 9 m, multipoint for two devices at once, SBC and AAC, plus aptX Adaptive with Snapdragon Sound devices. Google Fast Pair and Spotify Tap are supported. A 3.5 mm to 2.5 mm analogue cable is also in the box for aircraft systems and older devices.
Battery and automatic standby
Bose quotes up to 30 hours of playback, about 23 hours with Immersive Audio on, and up to 45 hours with noise cancelling switched off. A full charge takes about 3 hours, and 15 minutes adds about 3 hours of playback. The QuietComfort Ultra 2nd Gen White Smoke needs no power button: put the headphones on and they start. They disconnect after 10 minutes off your head and drop into low-power sleep after 30 minutes; laying them down with the ear cups facing up or folding them into the case enters a deep standby that Bose says can last for months, so they are not empty when you pick them up after a trip.
Who This Is Not For
The QuietComfort Ultra 2nd Gen White Smoke is not for workouts or rain: Bose lists no IP rating and advises avoiding situations where it may get wet. At about 264 g it is heavier than earbuds. The analogue jack on the headphones is 2.5 mm, so a standard 3.5 mm cable will not fit if you lose the supplied one. aptX Adaptive does not work with iPhone, lossless audio is limited to 16-bit/48 kHz over USB-C, no power adapter is included, and the pale cushions need regular cleaning.
