Timekettle W4 Plus AI Interpreter Earbuds

The Timekettle W4 Plus are true wireless earbuds that double as a real‑time AI interpreter for conversations, calls and media. Paired with the Timekettle app and powered by the company’s Babel OS 3.0, the W4 Plus can recognise and translate dozens of languages and accents, with special modes for one‑on‑one conversations, meetings and phone calls.

They combine translation features with everyday headphone functions: a hybrid voice pickup system (bone‑conduction sensor plus external microphones) and noise‑cleaning algorithms (VoiceFocus/BoostClean) for clearer speech, Bluetooth 5.3 connectivity and large dynamic drivers for robust audio. Battery life is rated at more than three hours of continuous translation per charge, extending to about 12 hours with the charging case, and up to 18 hours total for music playback — useful for travel and long meetings.

W4 Plus is aimed at frequent multilingual communicators who want a compact in‑ear translation tool that also serves as a capable pair of Bluetooth earbuds for calls and media.
