This is not a 'review', this is a shameless, paid for, ad, masking as 'review'. A real REVIEW of 'translation' earphones would review the... quality of translation, for starters. And also, would mention what translation engine or which AI service this translation is based on. It would also mention that it's not just 'heavy lifting' that's done by the phone, but that you need to have STABLE access to the 'internets', because the real heavy lifting is done not by your phone, but by some other people's computer(s), half the world away. A real review would mention not just 'privacy-mumble-mumble-something-mumble-privacy-aware-mumble', but would mention which business exactly so generously gives away (FREE! FREE!) 'ai' based translations. But hey, that would be a review, not a paid-for 4/5 star equivalent of amazon 'review'.
