EDITORIAL GUIDANCE

Isolation depends on fit and seal. A closed enclosure alone does not establish measured noise reduction.
Battery figures are manufacturer claims, not HeadphonesBase measurements. Wireless latency, codecs and call quality depend on the source device and mode.

Use-case tags are based on documented design and intended applications. They are not a lab rating.
