Source15Reviewsoundguys.com/nothing-ear-3a-review-159720Read 8 October 2026July 17 review reports four full-charge rundown tests around ten hours each, with the original waveform reaching the ten-hour mark. Stored 10 h is the published rounded approximate observation, not a calculated mean or invented seconds. Critically ANC was actually off because the wear sensor did not trigger in the normal laboratory setup, despite intended ANC testing. The review used a manufacturer-provided unit plus a separately purchased sample over four days. It does not identify which sample produced the displayed run, firmware, codec, host or playback level. These remain unknown. Its guessed six-hour ANC estimate is not a measured result.

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.

Rows with_case true are combined earbuds and case recharges. Talk rows are ANC-off 6 h / 25 h. Separate ANC-on talk 4.5 h / 18 h is stated here because the call enum cannot visibly distinguish ANC states. No call codec is assigned. Maker test conditions are 50 percent volume and Nothing laboratory 25 C. Its generic AAC test disclaimer is not used to relabel the explicitly LDAC rows. Other settings are default, and Snapshot pre-recording can increase power consumption. TechRadar mixes LDAC and talk figures in its generic battery table, so that table does not override these exact mode/codec claims.

80min2Maker product pagecheckout-my.nothing.tech/products/ear-aRead 8 October 2026Disclaimer 10 directly states 80 minutes for the earbuds to charge inside a case that is not connected to external power. Nothing lab conditions are 25 C and Nothing Power 45 W for the separate externally powered test. The 90-minute combined earbuds-and-case result is not stored as case-only timing.

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.

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.
