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.

Fast charging needs a 5 V / 1.5 A adapter or higher, per the maker's footnote. Quick charge: 10 minutes gives up to 10 hours of playback with the case, ANC off. The 45 W Nothing Power charger was used for the maker's charging tests.1Maker product pageus.nothing.tech/products/earRead 23 October 2026

The maker estimates about 1.5 hours for a full earbud charge in the case, about 3 hours for the case by cable, or 3.5 hours for the case wirelessly. Ten minutes of charging is claimed to provide four hours of earbud playback. The manual lists a 5 V / 0.8 A input. Use a certified USB-C charging cable and fully dry the buds and charging port first. ANC, LDAC, calls and volume affect runtime. LDAC and multipoint cannot be used together.2Maker product pagesoundcore.com/products/liberty-4-nc-a3947z11Read 8 October 2026Component-specific full-charge times come from the current maker FAQ. The original manual table only says up to 3 hours without component scope, so that generic table alone does not establish earbud-only timing. Input 5 V / 0.8 A is literal. No accepted charging watts are derived. Current A3947C guide separately lists a compatible Anker A2337 30 W adapter, which is not a bundled adapter or device input rating.

5.2g(0.2 oz)1Maker product pagesoundcore.com/products/liberty-4-nc-a3947z11Read 8 October 2026Current maker specifications state 5.2 g without case for the earbud. Tip size is not named. SoundGuys lists 5.7 g per bud without claiming that value as a measurement, so it is not imported into the measured-weight field or substituted for this maker claim.

Warranty

Manufacturer warranty (source market)iThe maker's warranty period for the exact SKU or configuration and market named in the source note. It applies only to that stated market, not every regional variant. Statutory consumer rights are excluded. The base term is stored. An extension that needs registration goes in the source note.

Its additional-consumer-rights note distinguishes the warranty from statutory rights. Optional paid soundcore Care is separate.
