IFA 2025 has been a stage for bold innovations this year, and among the standouts is Timekettle’s latest announcement. Known globally as a pioneer in AI-powered translation, the company has officially introduced the W4 AI Interpreter Earbuds. This first-of-its-kind wearable combines bone-voiceprint sensor technology with LLM-powered AI translation.

Timekettle’s goal is clear: break down language barriers with speed, accuracy, and natural conversation flow. With a promise of 98% accuracy and an almost imperceptible 0.2-second lag, the W4 isn’t just an incremental upgrade; it’s a leap forward in real-time multilingual communication.

Available starting 5th September 2025, at $349 / €349, the W4 will be on display at the Timekettle booth (Hall 3.2 – Stand 143) throughout IFA.

Why the W4 Matters: From Pro Tools to Everyday Use

Timekettle has already won professionals over with its W4 Pro AI Interpreter—an over-ear solution designed for business, conferences, and high-stakes multilingual environments. Now, the brand is widening its reach with the W4 in-ear model, optimised for casual, on-the-go communication.

These earbuds are smaller, lighter, and more stylish, available in Navy Blue and Sandy Gold, making them as much a lifestyle accessory as a translation tool. 

Breaking Barriers with Bone-Voiceprint Sensors

The real magic lies in the bone-conduction voiceprint sensor. Unlike standard microphones, it detects vibrations directly from the user’s bones, bypassing noisy environments.

This means:

• Crystal-clear translation even in airports, conferences, or crowded city streets.

• No sound leakage, making conversations more private and secure.

• Fewer errors, thanks to more precise voice capture.

Timekettle also refined the ergonomics: the W4’s ear hook positions the mic closer to the mouth, while the in-ear fit ensures comfort for long sessions without constant readjustments.

AI Translation That Feels Human

At the heart of the W4 is Babel OS 2.0, Timekettle’s proprietary AI-driven platform. Powered by advanced LLMs, it doesn’t just translate—it interprets.

Here’s what sets it apart:

• Context-aware translations that fix homophone errors (think “write” vs. “right”).

• 42 languages and 95 accents supported, covering 95% of global regions.

• Adaptive learning which tailors translations to user habits and conversations.

Future updates promise even more personalisation, including AI-powered voice cloning coming in 2026.

Key Features at a Glance

• Bone-Conduction Voice Capture – Eliminates background noise for ultra-accurate pickup.

• Smooth Conversations – Automatic switching between listening and speaking modes.

• Real-Time Global Reach – Translate 42 languages and 95 accents with near-zero lag.

• One-Flip Sharing – Instantly share an earbud for two-way translation.

• Battery That Lasts – 4 hours of continuous translation (10 hours with charging case), or up to 18 hours of music playback.

• Entertainment Ready – Not just for work—the W4 doubles as high-quality music earbuds.

The Bigger Picture: Timekettle’s Growing Ecosystem

The W4 doesn’t arrive in isolation. It extends Timekettle’s already strong lineup, which includes:

• W4 Pro – Professional-grade over-ear interpreter earbuds.

• WT2 Edge / W3 Earbuds – Consumer-friendly wearable translators.

• X1 Interpreter Hub – A multi-device platform for group translation.

• T1 and T1 Mini – Compact solutions for quick, casual translations.

By adding the sleeker, lifestyle-friendly W4, Timekettle is clearly aiming at a broader audience—bridging the gap between professional interpretation and everyday multilingual communication.

Final Thoughts

The W4 AI Interpreter Earbuds are more than just another gadget—they signal a new era where AI, bone-conduction, and wearable design merge to make real-time translation feel seamless and natural.

Whether you’re a globetrotting traveller, a student abroad, or someone who just wants to connect without language getting in the way, the W4 looks like the most advanced—and stylish—solution yet.

The earbuds launch on 5th September 2025, available via Timekettle’s official site and Amazon. If Timekettle delivers on its promises, the W4 may just redefine how we communicate across cultures.
