Overview

• The in‑ear W4 AI Interpreter earbuds are on sale today for $349/€349 via Timekettle’s website and Amazon, offered in Navy Blue and Sandy Gold.
• Timekettle says the system supports 42 languages and about 95 accents with up to 98% accuracy and roughly 0.2‑second lag.
• A bone‑conduction voice sensor detects jawbone vibrations to isolate the wearer’s speech in loud environments and enable quieter, more discreet talking, the company says.
• Battery ratings are up to four hours of continuous translation per charge (10 hours with the case) or up to eight hours of music playback (18 hours with the case).
• Positioned as a smaller, consumer‑focused follow‑on to the W4 Pro, the W4 adds a flip‑and‑share one‑on‑one mode and app tools like offline language packs and saved transcriptions, with AI voice cloning planned for next year.
