Bose put the strongest noise cancellation in the category into a pair of earbuds, then gave them six hours of battery.
Almost every argument for and against these earbuds comes out of that one sentence. The second generation did not change either half of it.
The verdict, before the details
If the noise is the whole problem โ a subway carriage, a bus, a cabin at cruise โ nothing at this price removes more of it. If you listen for longer than six hours at a stretch, buy something else.

Bose has been building cancellation hardware longer than anyone else selling earbuds, and the QuietComfort line is where that work lands.
The second generation is a refinement, not a redesign. The cancellation improved slightly, the tips sit a little deeper, and reviewers who compare buds for a living put it at the top of the class for outright quiet.
Everything else on the spec sheet is competitive rather than leading. That is the honest shape of this product.

What the numbers buy you
CustomTune remeasures your ear every time you put them in
Cancellation depends on seal, and seal changes with the shape of the ear canal and how deep the bud sits that morning.
Bose plays a tone at insertion, measures what comes back, and adjusts both the EQ and the cancellation to what it heard. That is why the quiet holds up between one wearing and the next instead of drifting.
Six hours means a commute, not a workday
Six hours with cancellation running covers a round trip and a long flight leg. It does not cover a day at a desk.
Turn on Immersive Audio and the figure drops to four. A 20-minute top-up in the case returns two hours, which is the number that actually rescues an evening.
The call microphones are the quiet second reason to buy
SpeechClarity separates your voice from the noise around it before it sends anything, and call clarity in noisy places is the strength reviewers name most consistently after the cancellation itself.
If you take calls from a platform or a pavement, that matters more day to day than a codec does.

Two drawbacks worth knowing
The battery lost the argument and did not come back to it
Sony's WF-1000XM6 runs eight hours with cancellation on. Apple's AirPods Pro 3 claim a similar figure. Bose stayed at six through a full generation change.
The buds are big, and they stick out
The housing is unchanged in shape and sits proud of the ear. Reviews from long-session listeners mention pressure after a few hours, and the pause tap is sometimes read as a volume slide instead.
Who this fits
This is a good fit if you
- Commute or fly through steady, low-frequency noise and want the most of it removed
- Take calls in loud places and need to be understood the first time
- Charge in a case through the day rather than listening straight through
Look elsewhere if you
- Wear earbuds for more than six hours without a break
- Have small ears or dislike anything that protrudes past the outer ear

What to pay
List is $299, and there is little reason to pay it. Prime Day and Black Friday have taken $50 to $80 off this line repeatedly, and the pattern has held across generations.
Nothing about the product changes in a sale. If you are not replacing a dead pair this week, waiting is the cheapest upgrade available.

Questions people ask before buying
Is the 2nd Gen worth upgrading to from the 1st Gen?
If you own the first generation, no. The cancellation gain is small, the battery is identical, and the shape has not changed. The upgrade case only makes sense coming from something older.
Does six hours of battery mean I charge them every night?
Only if you listen for six hours. The case holds 24 hours and a 20-minute stop returns two hours of play, so most commuters charge the case twice a week and never think about the buds.
How much noise will these actually remove?
Most of the low, steady kind and much less of the human kind. Our explainer on how active noise cancellation works covers why engine drone disappears while the conversation behind you does not.
