Timekettle unveiled its latest innovation, the W4 AIInterpreter Earbuds, at IFA 2025 in Berlin. These are the world's first bone-conduction interpreter earbuds, featuring a bone-voiceprint sensor that captures speech vibrations before sound leaves the body, enabling the system to bypass background noise and reduce latency.
Spoken at the launch, Leal Tian, CEO of Timekettle, emphasized the human impact of reducing latency: "This removes the psychological barrier of 'waiting for translation' and makes the technology fade into the background. It's about enabling people to focus on each other, on true human connection, rather than the device."
Timekettle claims 98 percent translation accuracy with a delay of just 0.2 seconds, even in noisy environments like subway stations or crowded trade shows. Combined with Babel OS 2.0's context-aware AI, the earbuds not only translate in real-time but also self-correct homophones and contextual errors, reducing clarification time in negotiations by up to 50 percent.
The W4 supports 42 languages and 95 accents, with modes designed for one-on-one conversations, family communication, and international business meetings. In "Listen & Play" mode, users can participate in multilingual conferences, featuring full audio recording, meeting summaries, and a four-hour battery life that ensures uninterrupted use.
Widely described as the closest realization yet of the sci-fi "Babelfish," the W4 drew attention with its promise of near-instant translation and its consumer-ready design.
Visitors to the booth were able to test the earbuds in various scenarios, ranging from casual conversations to simulated boardroom exchanges. Many were struck by the combination of professional-grade performance and consumer portability, with a design available in Midnight Blue and Sandy Gold finishes.
Beyond translation, the W4 doubles as a music and lifestyle accessory, offering high-quality audio and an ergonomic fit with a tilted stem designed for all-day comfort. Timekettle also announced that the earbuds come with lifetime free upgrades, ensuring the system evolves with advances in AI without added cost, making it attractive for both individual users and enterprise deployment.
Priced at $349 / €349, the W4 AI Interpreter Earbuds are available immediately through Timekettle's official website and Amazon.
