Timekettle has introduced its latest device at IFA 2025 in Berlin: the W4 AI Interpreter Earbuds, compact in-ear buds designed for seamless real-time translation. Priced at $349/€349, the W4 earbuds are available now through Timekettle’s official site and Amazon.
Bone-Voiceprint Sensors for Clearer Speech
The W4 earbuds stand out by incorporating bone-voiceprint sensors, which capture vibrations directly from the user’s bones rather than relying solely on external microphones. This design minimizes background noise and prevents sound leakage, making the earbuds useful in noisy environments like airports or convention halls. A specialized ear hook ensures microphones stay in position, giving users consistent, high-clarity speech pickup.
Translation Accuracy with AI Context Awareness
Running on Babel OS 2.0, Timekettle’s AI-driven translation platform, the W4 delivers near-human translations with 98% accuracy and just 0.2 seconds of lag. The system supports 42 languages and 95 accents, automatically switching between listening and speaking modes to keep conversations natural. One feature worth highlighting is its ability to distinguish between homophones—words that sound alike but carry different meanings—thanks to advanced LLM-powered contextual processing.
Features for Travelers and Daily Use
Timekettle has positioned the W4 as a more portable alternative to its W4 Pro over-ear model, targeting casual users and leisure travelers. Available in Navy Blue and Sandy Gold, the earbuds also double as regular wireless headphones, offering:
- Effortless sharing: open the case, pass an earbud, and start a two-way translated conversation.
- All-day use: 4 hours of translation (or 8 hours of music) per charge, expandable to 10 hours of translation with the charging case.
- Music and language fusion: high-quality playback in addition to interpretation.
Expanding the Timekettle Portfolio
The W4 joins a growing line of devices including the W4 Pro, WT2 Edge/W3, X1 Interpreter Hub, and T1 Mini. Timekettle’s CEO, Leal Tian, noted that the W4 reflects the company’s vision of making real-time, AI-powered interpretation feel as natural as speaking with a live translator.
