Timekettle Unveils W4 Plus AI Interpreter Earbuds at IFA 2026

BERLIN, At the International Fair for Audio-Visual Media (IFA) 2026, Timekettle, a global leader in AI-powered translation, introduced the W4 Plus AI Interpreter Earbuds, a significant upgrade to the compact W4 platform. These earbuds, designed for global business, travel, and everyday communication, combine face-to-face translation, live listening, real-time call interpretation, and multimedia translation into a single, portable device.

The W4 Plus offers a seamless user experience, enabling users to switch effortlessly between in-person conversations, international phone calls, online meetings, conferences, and foreign-language content without needing to switch devices. Integrated AI features assist users in understanding specialized terminology, maintaining context during longer conversations, and transforming translated meetings into concise summaries and key takeaways.

Powered by Babel OS 3.0, the W4 Plus supports 52 languages and 106 accents online, with 13 offline language pairs. The earbuds leverage Timekettle’s bone-conduction voiceprint sensing, dual microphones, and the new VoiceFocus algorithm to provide clearer speech capture in both noisy and quiet environments. Users can expect a 32%-47% improvement in low-volume voice pickup compared to the original W4.

The W4 Plus comes in two versions: the full-feature model priced at $379 and the W4 Plus Subscription Version at $299. Visitors can experience the earbuds at the Timekettle booth 164 in Hall 3.2 throughout IFA 2026.

AI Tools Enhance Translation Experience Beyond word-for-word translation, the W4 Plus includes several AI-powered tools to enrich the user experience. These include AI Specialized Translation, which allows users to select from industry profiles such as General, Tech & Internet, Manufacturing & Industry, New Energy & Green Tech, and Biotech & Pharma. This feature helps improve accuracy in specialized discussions.

AI Conversation Memory maintains context across longer conversations, ensuring consistent terminology and meaning. AI Live Summary converts saved conversations and meetings into concise summaries and key takeaways for easier review. The AI Lab (Personalized Language Experience) offers additional features like a Personal Glossary for customized terminology, Style Translation for adjusting the tone of translations, and an AI Speaking Coach for practicing real-world conversations.

Clearer Voice Pickup Without Speaking Up The W4 Plus builds on the W4's bone-conduction voiceprint sensor with an upgraded voice pickup system that combines bone-conduction sensing, dual microphones, and the enhanced VoiceFocus technology. This system helps isolate speech in crowded environments while also improving recognition for softer voices in quieter locations.

Founder and CEO Tian Leal commented, "W4 Plus takes everything users loved about W4 and makes translation smarter, clearer, and more natural. With upgraded Babel OS 3.0, enhanced VoiceFocus technology, and new AI capabilities, W4 Plus delivers better voice pickup, stronger contextual understanding, and a more natural translation experience, helping people communicate across languages with less friction."

Compact Design with All-Day Power Each W4 Plus earbud weighs 5.7 grams and features a semi-in-ear design for extended comfort. The earbuds and charging case have a combined weight of 116.5 grams. Each earbud provides more than three hours of continuous translation, while the charging case extends total translation time up to 12 hours and supports up to 18 hours of music playback.
