W4
AI Interpreter Earbuds
A more focused way to translate face-to-face conversations, with bone-voiceprint pickup designed for busy environments.
- 52 languages and 106 accents
- Bone-voiceprint pickup
- Selected offline translation
WHY IT STANDS OUT
Focused on the person
in front of you.
Built for real conversations
Share the earbuds in One-on-One mode or listen and respond through the app when sharing both earbuds is not practical.
Translation beyond one language
Online coverage reaches 52 languages and 106 accents, while a smaller set of language pairs can be downloaded for offline use.
VOICE TECHNOLOGY
Your voice is
the starting point.
Traditional microphones can struggle when several people are speaking or background noise becomes loud. The W4 combines a bone-voiceprint sensor with conventional microphones and vector noise cancellation to help isolate the wearer’s speech.
It is designed for situations such as cafés, busy streets and public spaces, though real-world translation quality still depends on noise, accents and context.
TRANSLATION MODES
Different situations.
Different ways to communicate.
One-on-One Mode
Two people each wear an earbud and speak in their own language while the connected smartphone manages translation.
Listen & Speak Mode
Listen to another person and respond through translation when sharing both earbuds is not the right fit for the situation.
LANGUAGE COVERAGE
Online breadth.
Offline essentials.
The W4 uses the Timekettle app for online translation across 52 languages and 106 accents. For limited-connectivity situations, Timekettle lists 13 downloadable offline language pairs.
Offline translation does not cover every online language or accent. Check the supported pairs before traveling.
BUILT FOR EVERYDAY USE
Translation when you need it.
Earbuds when you don’t.
The W4 also works as Bluetooth earbuds for music and ordinary calls. Its compact charging case is designed to travel with your phone rather than replace it.

WHAT YOU SHOULD KNOW
Useful context
before deciding.
The W4 is most convincing when its limits are understood as clearly as its strengths.
You will need a smartphone
The W4 relies on the Timekettle app and is not designed as a fully standalone translator.
Offline support is more limited
The full online language selection is not available offline. Confirm the supported language pairs before travel.
Some advanced features may cost more
Optional iOS features such as multimedia and voice-call translation may require the W4 Unlimited subscription. Check current pricing and compatibility with Timekettle.
AI translation is not perfect
Noise, accents, specialized vocabulary and context can affect results. Verify important information rather than relying only on automatic translation.
