TimeKettle W4 Plus TWS Translation Earbuds

The black TimeKettle W4 Plus is a pair of wireless TWS translation earbuds that make communication easier during business meetings, travel, and everyday conversations with people who speak different languages. The device supports real-time translation of 52 languages and 106 accents, using the Babel OS 3.0 system and AI algorithms that improve the fluency and naturalness of the translation. Users have access to 4 communication modes, bone conduction technology supported by a dual-microphone system, Bluetooth 5.3 connectivity, and up to 12 hours of battery life with the charging case. The lightweight design and regular OTA updates make the W4 Plus ideal for both work and travel.

Clear voice capture even in noisy environments

The earbuds are equipped with bone conduction technology and a hybrid dual-microphone system. The VoiceFocus algorithm, working in tandem with these features, effectively captures the user’s voice and reduces the impact of ambient noise. This ensures smoother conversations during conferences, business meetings, at airports, or in other high-noise environments.

Babel OS 3.0 – Fast and Natural Translations

The headphones are powered by the proprietary Babel OS 3.0 system, which automatically selects the appropriate translation engine, ensuring smooth operation even with a less stable internet connection. The platform supports online translation in 52 languages and 106 accents, as well as select language pairs in offline mode. Built-in AI algorithms improve the naturalness of translations, making conversations sound more casual and better conveying the intended meaning.

Four Communication Modes

The TimeKettle W4 Plus offers 4 communication modes that let you tailor the translation method to different situations. One-on-One mode enables face-to-face conversations—each person uses one earpiece, and translation occurs simultaneously for both speakers. Listen & Play is ideal for lectures, presentations, and meetings, allowing you to listen to the translation in real time. The earbuds also support Voice Call Translation—translating phone and internet calls—as well as Multi-Media Translation, which translates audio and video content.

Smart AI Features

The TimeKettle W4 Plus uses artificial intelligence to streamline communication during international meetings and conversations. The system recognizes specialized terminology from various industries, helps maintain consistency in translations during longer conversations, and remembers user preferences. Additionally, the meeting summary feature allows you to quickly revisit key information without having to take notes manually.

All-Day Comfort

Each earbud weighs just 5.7 g, while the entire set with the carrying case weighs 116.5 g, so it easily fits in a pocket or bag. The ergonomic semi-in-ear design ensures comfort even during hours of use. The set also includes interchangeable ear tips and ear hooks, which make it easy to customize the earbuds to your individual preferences.

Up to 12 hours of battery life with the case

The earbuds provide up to 3 hours of continuous translation, while the charging case extends the total battery life to 12 hours. It takes about 50 minutes to charge the earbuds, while a full charge of the case takes about 1.5 hours. The USB-C port allows you to conveniently recharge them both at home and while traveling.

Secure communication and regular updates

The TimeKettle W4 Plus was designed with user privacy in mind. The manufacturer declares compliance with the European General Data Protection Regulation (GDPR) and the U.S. Family Educational Rights and Privacy Act (FERPA) regarding data protection in the education sector. Data is transmitted using encrypted communication, and the manufacturer states that it is neither stored nor used to train AI models. The device also supports OTA (Over-the-Air) updates, which allow the translation system, language library, and earbud features to be developed and improved without having to connect the device to a computer.
