There is some technology that I’ve been begging to hurry up. My other half is German and despite my best efforts, the language escapes me (fortunately her English is pristine). But I’ve always been left wondering why technology is so slow to advance with translation, but advancing it is.
AI-platforms are fantastic for the advancement of translation technology, both in phones and in new devices. Which is why I’m excited about the prospect of Timekettle’s new W4 AI Interpreter Earbuds.
Timekettle, which admittedly has a slightly confusing name which has been inspired by the Hitchhiker’s Guide to the Galaxy’s Babel Fish, is building on the company’s reputation in AI-powered translation with the W4 earbuds are designed to make real-time cross-language communication faster and more natural.

The W4 stands out for its bone-voiceprint sensor technology, which captures speech through vibrations in the user’s bones. This helps eliminate background noise, making it easier to communicate in busy environments like airports or conferences. Combined with AI-powered, context-aware translation, the device is capable of distinguishing between phonetically similar phrases and promises 98% accuracy with a near-zero lag of 0.2 seconds.
The earbuds support translation across 42 languages and 95 accents, enabling conversations with speakers from over 95% of the world’s regions. A simple case-flip mechanism allows users to share an earbud for instant two-way translation.
Beyond translation, the W4 also functions as everyday earbuds, offering up to four hours of continuous translation or eight hours of music playback on a single charge. With the charging case, this extends to 10 hours of translation or 18 hours of music.
Priced €349, the W4 earbuds are available through Timekettle’s website and Amazon.
