ANC with Dolby is five hours earbuds-only. Calls with ANC are 5.5 hours for both earbuds, versus 4.5 hours single-earbud use. The four-hour Dual Connections with LDAC/Dolby entry does not state ANC or distinguish the slash conditions, so it remains visible guidance rather than an invented row. Codec and spatial state are omitted for generic runtime rows.

Charging guidanceiPublished charging guidance or estimates that do not separate earbuds and case. Preserve the maker’s component scope and limits. Do not assign an unspecified or combined estimate to a component-specific numeric field.

The guide estimates up to 60 minutes for earbuds and three hours for the charging case with earbuds by USB-C, or four hours wirelessly. The FAQ separately estimates about 50 minutes for earbuds, two hours for an empty case by cable, 2.5 hours with earbuds, and 3.5 hours for an empty case wirelessly. These are maker estimates with different component scopes and unspecified test details. Input is 5 V 0.8 A. Dry the earbuds and USB-C port before charging. Ten minutes of earbud charging in the case claims up to five hours of playback, with ANC, codec and Dolby settings unspecified.
