What happened
Which?, the UK consumer organization, published a test of Apple's Live Translation on 28 July 2026. The feature translates speech from another language through AirPods in real time and shows the translation in Apple's Translate app. Which? asked four bilingual speakers to chat in Italian, Spanish, German and French. It judged the translation through AirPods Pro 3 and in the app, with background noise in half of the tests. Which? found that the translation was generally accurate in all four languages. A few words were lost and some sentences were ungrammatical, but the testers could still understand what was meant. The French translation was excellent. The Spanish one translated word for word and slowed down with background noise. The Which? scientific advisor who led the tests said that the delay made natural conversation difficult. The article gives no error counts. Testaankoop of Belgium had tested the feature for an article published on 8 March 2026. It found that bugs in iOS 26.1 made the feature unstable and that it lagged by 4 to 6 seconds when it worked.

Which? (Humairaa Habib). We tested Apple's Live Translation feature: does it really work? 28 July 2026. Which? tested the feature on AirPods Pro 3 with four bilingual speakers, in quiet conditions and with background noise. Section 'Verdict: is Apple's Live Translation worth it?'
We found the translation was generally accurate across all of the languages we tested. A few words got lost in translation and there were some grammatical inconsistencies, but we could still understand what was meant.

Testaankoop (expertise Richard Motte, editing Evelien De Bal). Beste vertaal oortjes: onze test van translator earbuds en hun werkelijke prestaties. 8 March 2026. Section on ordinary earbuds with built-in translation, on Apple Live Translate on AirPods Pro 3, tested under iOS 26.1. In the quoted passage, Testaankoop lists instability, an unnatural voice and patchy availability as drawbacks. It concludes that the feature may be stronger in the future but is still too unstable for daily use. Cited as a contrary finding from an earlier test.
Nadelen: instabiel, onnatuurlijk stemgeluid, niet altijd beschikbaar. Conclusie: Mogelijk sterker in de toekomst, nu nog te onstabiel voor dagelijks gebruik.

Live Translation uses Apple-built models that run entirely on device, so your personal conversations stay private.

AI system
- Workflow
-
Which? Tested Live Translation on AirPods Pro 3 with four bilingual speakers who chatted about topics such as their holidays. Which? Judged the in-ear translation and checked its accuracy in Apple's Translate app. Half of the listening tests had background noise, and the other half took place in a quiet meeting room.
- Relation to AI
-
Which? Judged the translations themselves and ran no comparison with and without the feature, so the results describe Live Translation's own output. Which? Notes that the feature needs Apple Intelligence but does not describe the models behind it. Apple states in its iPhone User Guide that Live Translation uses Apple-built models that run entirely on the device. In a footnote on the same page, Apple states that Apple Intelligence uses generative models. Generative models are trained on data. Apple does not name the translation models or say how it trained them.
Follow-up
- Conditions for replication
-
The user has supported AirPods and an iPhone 15 Pro or later running at least iOS 26.0 with Apple Intelligence enabled. Both people speak one of the nine languages that the feature supports. The speakers accept short delays, which grew with long or complex sentences and with background noise in the Which? Tests.
