Stored 10 h is the published rounded approximate observation, not a calculated mean or invented seconds.

Feature	Needs
LDAC playback	Compatible Android source with LDAC enabled. The maker lists Android 8.0 or later and iOS 13 or later for device compatibility. iOS uses AAC rather than LDAC.
Audio Snapshot	Nothing X account. Capture up to one minute of source-phone audio, optionally including the preceding 30 seconds. Snapshot stops automatically at the selected duration. Pre-recording increases power use. Recorded audio syncs to Nothing X on Android or iOS.
Call Recording	Nothing X account and a supported region, including the United States. Disabled by default until enabled after the app region check. Record up to two hours of calls or online meetings, with an audible notification.
Cloud Pro transcription	Internet connection and Nothing X account. Current maker offer includes 120 minutes monthly for the first three months. Continuing cloud Pro access requires a subscription. Exact pricing is only shown in the app.
Essential Space integration	Select Nothing devices with an Essential Key and current software. Ordinary recording does not universally require a Nothing phone.
Low Lag Mode	Game Mode on a compatible Nothing phone, or enable through Nothing X. Under-120-ms support wording differs from an as-low-as-120-ms product disclaimer, so no exact latency is stored.

The article How long do Sleepbuds 2 take to charge gives the same figure. The Sleepbuds charge only in the Smart Case. Maker estimate, not a measurement.

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 maker gives an unspecified-component USB-C full-charge estimate of 70 minutes and recommends a 5 V / 1 A or higher adapter. Five minutes in the case is claimed to provide one hour of earbud playback with ANC off. The specifications separately give ten minutes for ten hours including case recharges. A marketing footnote instead describes ten hours from the earbuds after ten minutes, so that component scope is unresolved. The original B190 safety booklet specifies a charger output range of 2.5 to 5 W. These are maker estimates and guidance, without an earbud-only or case-only full-charge time.2Maker product pageus.nothing.tech/products/ear-3aRead 8 October 2026Current Specs Charging table says Type-C wired charging-to-full time 70 minutes without a separate component label. Disclaimer says Ear (3a) 0 to 100 percent when the case is connected, with Nothing Power 45 W at 25 C. The test adapter rating is not device input power. Dedicated fast-charge support confirms 5 min / 1 h earbuds-only and 10 min / 10 h buds plus case. A conflicting 10-minute full-earbud implication in the marketing footnote and reviewer paraphrase is preserved here without assigning a numeric full-bud time.

The Smart Case holds an additional 2 to 3 charges for the earbuds.
