Bottom Line

Choose if you want class-leading ANC and a punchy, high-detail sound; Skip if you have small ears or expect all-day battery and a bargain price.

Best for

Frequent travelers and commuters who prioritize the strongest noise cancellation and an energetic sound, and who want premium features like multipoint and wireless charging.

Not for

People with very small ears, anyone chasing best-in-class battery life or a compact case, and listeners who need a powerful multi-band EQ to reshape the stock tuning.

Verdict

Bose refines its flagship formula with truly top-tier noise reduction, a lively, bass-forward sound that still pulls out detail, and a comfortable, secure fit for most ears thanks to the tip-and-wing system. Wireless charging and reliable multipoint make day-to-day use smoother, and call performance is generally improved, especially in noisy places. The tradeoff is that the buds and case are on the large side, battery life remains merely average, and the Bose app EQ is still limited, so serious tuners may feel boxed in. Touch controls are responsive, but can be a little too sensitive for some people.

FAQ

How strong is the ANC compared to other premium earbuds?

Across reviews, it is consistently described as class-leading and among the best (often the best) at reducing both low rumble and a wide range of everyday noise.

Does the case support wireless charging and USB-C?

Yes. Wireless charging is a key Gen 2 upgrade, and USB-C charging is also supported.

Is multipoint actually useful in real life?

Yes. Reviews generally report smooth switching between two connected devices, though some note it works best when you pause audio on one device before starting on another.

Are these good for calls outdoors or in noisy places?

Call clarity is often rated as improved and strong, with effective background-noise suppression, but a few tests still found wind and heavy noise can slip through depending on conditions.

What battery life should I expect?

Expect around 6 hours with ANC, less with immersive/spatial modes (often cited around 4 hours), with multiple recharges from the case bringing total use to roughly a full day for most people.
