Key Features
Bose's Best-Ever ANC + ActiveSense
The second generation refines what was already the industry benchmark: ActiveSense smooths sudden spikes — a train arriving, a slammed door — rather than only holding back steady background hum. Quiet Mode seals you off; Aware Mode keeps the world audible.
Lossless USB-C Audio (new to 2nd gen)
Plug the USB-C cable into a phone or laptop and audio runs at 16-bit / 44.1–48kHz lossless, bypassing Bluetooth compression entirely. For focused listening, editing work or a plane's entertainment system — this is the feature the first gen never had.
aptX Lossless + Snapdragon Sound
With a Snapdragon Sound phone you get aptX Lossless wirelessly; gaming gets aptX Adaptive low latency. iPhone users keep every feature over Bluetooth and can take the USB-C cable for lossless.
CustomTune Personalisation
Each time you put them on, a test tone maps the shape of your ear canal and calibrates both sound and noise cancelling to it — not one tuning for everyone.
Immersive Audio + Cinema Mode
Immersive Audio pushes the stage outside your head — closer to speakers than to headphones. The new Cinema Mode tunes for video: dialogue anchored centre, ambience spread wide. Made for series marathons and films.
Comfort That Lasts the Full Charge
Plush cushions and a pressure-distributing headband — 30 hours of battery matched by all-day wearability. It is what the QuietComfort name has always meant.

Frequently Asked Questions
What changed from the first generation?
Battery 24 → 30 hours, quick charge 15 minutes now gives 3 hours instead of 2.5, plus new lossless USB-C audio and Cinema Mode, and further-refined ANC. Fit and look are close to unchanged.
How long does the battery last?
Up to 30 hours; about 23 with Immersive Audio on. A 15-minute charge gives roughly 3 hours; a full charge takes about 3 hours.
What is lossless USB-C audio?
Connect the included USB-C cable to a phone or laptop and audio streams at 16-bit / 44.1–48kHz without Bluetooth compression. You hear it most in focused listening — which is what this price tier is for.
Do they work fully with an iPhone?
Everything works over Bluetooth; aptX Lossless specifically needs a Snapdragon Sound Android phone. On iPhone, use the USB-C cable when you want lossless.
What colours are there?
Black, white smoke, midnight violet, driftwood sand and desert gold — all five currently in stock, all viewable at the showroom.
What listening modes are there?
Quiet (full ANC), Aware (transparency with ActiveSense spike control), Immersive Audio and Cinema Mode — switched and customised in the Bose app.
