Two questions settle this: how much noise you need gone, and which phone you carry.
The AirPods Pro 3 are the pick on an iPhone, and the reason is specific rather than brand loyalty: pairing, Find My, hearing-aid features and Live Translation are implemented in Apple's operating system, not in the earbuds, so on Android they simply are not there. Apple's own claim is up to twice the noise removed compared with the Pro 2, and that is Apple's figure rather than an independent measurement.
The Bose QuietComfort Ultra Earbuds (2nd Gen) are the pick when silence is the whole point. CustomTune plays a tone into each ear on every insertion and adapts the cancellation to the seal it actually got, which is why Bose keeps its lead on depth rather than on driver specifications. The cost is a six-hour battery, which is short for a long-haul flight, and IPX4, which is the weakest water rating here.
The CMF Buds 2a are the backup pair. They carry hybrid ANC and Dirac tuning at a fraction of the other two, and they are the easiest recommendation in the guide for a gym bag or a second set that you will not mourn.
Basis: published feature sets and manufacturer ANC claims, labeled as such, plus owner reviews and our own weekly price record. We have not worn these. Ratings score each product on the merits with price left out, so the premium pick always sits highest. The tier tells you where a pick sits on price, not how good it is.
