It does not categorically prohibit all concurrent LDAC/multipoint use, so multipoint_ldac is not set false. Current compatibility FAQ gives iOS 13 minimum, stronger than legacy full specifications iOS 11. Low-lag and Fast Pair conditions come from the original product page. An under-120-ms headline differs from the as-low-as-120-ms disclaimer, so no exact numeric latency is stored.16Maker product pagecheckout-my.nothing.tech/products/ear-aRead 8 October 2026Product-page Disclaimers 8, 15 and 16 give Nothing phone Game Mode, dual-connection and Google Fast Pair conditions.

Charging guidance
Charge the earbuds in the closed case. Use USB-C to charge the case, with a 5 V / 1.5 A or higher adapter. The maker reports 80 minutes for an earbud charge in an unplugged case and 90 minutes for an empty earbuds-and-case set charged together. Ten minutes gives up to 3.2 hours of earbud playback with ANC off, or 2 hours with ANC on. The separate case-inclusive quick-charge claim is 10 hours with ANC off and 6 hours with ANC on in support, while the product-page footnote says 9.5 hours with ANC off. These are maker laboratory estimates, not case-only charge times.6Maker product pagecheckout-my.nothing.tech/products/ear-aRead 8 October 2026Product-page Disclaimer 10 to 12 separates 80-minute buds and 90-minute combined timing, gives adapter guidance 5 V / 1.5 A or higher, and uses Nothing Power 45 W at 25 C. The adapter rating is not device input power. Disclaimer 12 gives 9.5 h case-inclusive after 10 minutes, conflicting with the 10 h headline and dedicated support article. Both source statements are retained without guessing a reconciliation.
