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

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 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.

Ear tip fit test

Yes14Reviewtechradar.com/audio/earbuds-airpods/nothing-ear-3a-reviewRead 8 October 2026Reviewer directly confirms an ear-tip seal fit test. The current maker FAQ titled earbud fit test describes a hearing assessment and compensation instead, while this review explicitly says the hearing-test personal profile remains flagship-only. hearing_test and sound_personalization remain unresolved and omitted pending clarification. The Advanced eight-band equalizer is not itself a hearing test. Generic touch wording is not used to override pinch controls.

SoundGuys gives 5 g and kopfhoerer.de gives 5.5 g. The 56 g on the maker page is the case with the earbuds, so no case weight is stored.
