Treble was often clear and detailed, but some reviewers noted sibilance, thin cymbals, reduced sparkle, or upper-register sharpness.

Passive isolation is praised when the fit is right, with reviewers noting strong physical blocking and seal benefits.

Passive isolation was considered good when fit was right and helped ANC performance, though it remained dependent on a proper seal.

Transparency mode is often praised as natural and lifelike, but a few reviewers mention hiss or that AirPods/Bose still perform better.

Transparency mode was mixed, from very good vocal/ambient awareness to bright, tinny, hissy, or limited adjustability.

Battery life is generally competitive and often praised, but some reviewers note it is not class-leading or may be short for some listeners.

Battery life was one of the strongest areas, with most reviewers reporting long sessions and strong case endurance despite LDAC or ANC reducing runtime.

Multipoint works well for some reviewers and makes device switching convenient, though one review only found it OK in limited testing.

Multipoint reliability was a major strength, with reviewers repeatedly describing device switching as seamless, reliable, or essential.
