Timekettle launched its new W4 PRO AI Interpreter Earbuds at IFA 2024 in Berlin. This device aims to address cross-language communication needs in various scenarios, from hosting foreign guests to conducting multilingual online meetings and traveling abroad.
The W4 PRO represents Timekettle’s latest effort in developing translation technology. It builds upon their previous products, which have evolved from handheld translators to earbuds capable of simultaneous interpretation.

Key Features and Modes
The W4 PRO offers three primary modes of operation:
1. One-on-One Simultaneous Interpreting:
- Instant translation for two-way conversations
- Dual interpretation system
- Triple microphone array for improved voice recognition
2. Listen & Play Mode:
- Designed for multilingual meetings

- AI Memo feature provides post-meeting summaries
3. Online Interaction Mode:

Design and Technical Aspects
The W4 PRO AI Interpreter Earbuds showcase a design that prioritizes user comfort and functionality. The earbuds feature an open-ear design, allowing for extended wear without the discomfort often associated with in-ear devices. This design choice not only enhances comfort but also addresses hygiene concerns and maintains environmental awareness for the user.
On the technical front, the W4 PRO boasts high-quality audio output. This ensures clear and crisp sound reproduction, which is crucial for accurate interpretation and communication. The earbuds incorporate advanced voice recognition technology, utilizing a triple microphone array to capture speech accurately in various environments. The W4 PRO is designed to handle multiple languages, catering to a diverse range of communication needs in our increasingly globalized world.

Potential Applications
- Business negotiations across language barriers
- Tourist communications in foreign countries
- Participation in multilingual meetings
- Consumption of foreign language media content
According to Timekettle CEO Leal Tian, the W4 PRO aims to facilitate more natural, hands-free conversations with eye contact, potentially making cross-language interactions smoother compared to using phone-based translation apps.
As of now, the Timekettle W4 Pro is globally available for purchase on the brand’s online shop at $449.
