W4 Pro AI Interpreter Earbuds: Best for Business
The W4 Pro is Timekettle's flagship product, designed as a "personal global business assistant." This isn't just marketing—the device is specifically built for professional scenarios that other translation earbuds can't handle.
Standout Features
1. Phone Call Translation
This is the W4 Pro's killer feature. You can take calls in your native language while the other person hears their language:
How it works:
├── Incoming call in any language
├── W4 Pro translates in real-time
├── You hear your language in your ear
├── Your response is translated before reaching caller
└── No special hardware needed on the other end
The "no device needed on the other end" is crucial—the person you're calling doesn't need any special equipment. The translation happens entirely on your end.
2. Online Meeting Translation
For remote work across language barriers:
- Translates and displays subtitles during virtual meetings
- Works with Zoom, Teams, and other platforms
- Compatible with phone and tablet
- Real-time subtitle overlay on your screen
3. Media Translation
Beyond conversations, the W4 Pro translates:
- News broadcasts
- TV series and movies
- Podcasts and audio content
- YouTube videos in foreign languages
It translates both video and audio from your phone, tablet, or computer with real-time subtitles.
Technical Specifications
- Languages: 43 languages, 96 accents
- Connectivity: Bluetooth 5.3
- Battery: 8 hours (earbuds) + 32 hours (case)
- Latency: 0.5-1.2 seconds
- Noise Cancellation: AI-powered adaptive
- App Required: Yes (iOS/Android)
Real-World Testing

The speed was impressive—conversation flowed naturally without awkward pauses.

W4 AI Interpreter Earbuds: World's First Bone-Conduction Translation
The W4 (non-Pro version) takes a different approach: bone-conduction technology for "in-depth cross-language communication."
What Makes It Unique

Unlike traditional earbuds that sit in your ear canal:
- Rests on your cheekbones

- More natural conversation feel
- Better awareness of surroundings
This design is specifically for face-to-face, extended conversations where you need to maintain eye contact and natural presence.
Best Use Cases

- Language learning sessions
- Cultural exchanges

Pricing
- W4 AI Interpreter Earbuds: $249
