Timekettle Unveils W4 Plus AI Interpreter Earbuds at IFA 2026, Bringing AI-Powered Translation to Conversations, Calls and Digital Content

The latest upgrade introduces Babel OS 3.0, enhanced VoiceFocus technology and AI-powered tools that preserve conversation context, improve voice clarity and transform multilingual conversations into actionable insights.

BERLIN, Sept. 4, 2026 /PRNewswire/ -- Today at IFA 2026, Timekettle, a global leader in AI-powered translation, unveiled the new W4 Plus AI Interpreter Earbuds, a significant upgrade to the compact W4 platform. W4 Plus combines face-to-face translation, live listening, real-time call interpretation and multimedia translation in one portable device.

Designed for global business, travel and everyday communication, W4 Plus allows users to seamlessly move between in-person conversations, international phone calls, online meetings, conferences and foreign-language content without switching devices. Integrated AI capabilities help users understand specialized terminology, maintain context during longer conversations and transform translated meetings into concise summaries and key takeaways.

Powered by Babel OS 3.0, W4 Plus supports 52 languages and 106 accents online, along with 13 offline language pairs. The earbuds combine Timekettle's bone-conduction voiceprint sensing, dual microphones and the new VoiceFocus algorithm to capture speech more clearly in both noisy environments and quieter conversations.

The full-feature W4 Plus is priced at $379, while the W4 Plus Subscription Version is priced at $299. The earbuds will be demonstrated throughout IFA 2026 at the Timekettle booth 164 Hall 3.2.

From Face-to-Face Translation to All-Day Global Communication

Introduced at IFA 2025, the original W4 brought Timekettle's bone-voiceprint sensing and context-aware translation into a compact semi-in-ear design. W4 Plus retains the same portable form factor while expanding translation scenarios through four integrated modes:

One-on-One Translation enables two users to each wear one earbud for natural, simultaneous two-way conversations.

Listen & Play supports live listening at conferences, lectures, presentations and guided tours, with audio saving, transcription and AI-assisted review.

Voice Call Translation provides real-time two-way interpretation for phone calls, video calls and online meetings across platforms including Zoom, WeChat, WhatsApp and Telegram. The other participant does not need an app or device, while bilingual transcription is displayed on the user's phone.

Multi-Media Translation translates audio and video content from platforms such as YouTube, Netflix and social media with synchronized translated subtitles.

Together, these modes allow users to move from everyday conversations to international meetings and foreign-language content without changing translation devices.

AI Tools Add Context and Continuity to Translation

Beyond word-for-word translation, W4 Plus uses AI to help users better understand terminology, context and key information during longer multilingual conversations.

AI Specialized Translation allows users to select industry profiles including General, Tech & Internet, Manufacturing & Industry, New Energy & Green Tech, and Biotech & Pharma, helping improve accuracy in specialized discussions.

AI Conversation Memory maintains context across longer conversations, preserving consistent terminology and meaning.

AI Live Summary converts saved conversations and meetings into concise summaries and key takeaways for easier review.

AI Lab (Personalized Language Experience) gives users greater control over communication. Features include Personal Glossary for customized terminology, Style Translation for adjusting translation tone, and AI Speaking Coach for practicing real-world conversations such as interviews, business meetings and travel scenarios.

Clearer Voice Pickup Without Speaking Up

W4 Plus builds on W4's bone-conduction voiceprint sensor with an upgraded voice pickup system combining bone-conduction sensing, dual microphones and VoiceFocus technology.

The system helps isolate speech in crowded environments such as trade shows, airports and conferences, while also improving recognition for softer voices in quieter locations. The upgraded VoiceFocus noise reduction algorithm improves low-volume voice pickup performance by 32%-47% compared with the original W4.

Babel OS 3.0 Delivers Faster, More Natural Translation

Babel OS 3.0 automatically selects the optimal translation engine for each language pair and leverages Timekettle's global service nodes to reduce latency and maintain stable performance.

An AI refinement layer improves translated speech by recognizing context and adjusting phrasing, helping conversations sound more natural rather than word-for-word. The system also switches seamlessly between online and offline translation to minimize interruptions.

"W4 Plus takes everything users loved about W4 and makes translation smarter, clearer and more natural," said Tian Leal, Founder and CEO of Timekettle. "With upgraded Babel OS 3.0, enhanced VoiceFocus technology and new AI capabilities, W4 Plus delivers better voice pickup, stronger contextual understanding and a more natural translation experience—helping people communicate across languages with less friction."

Compact Design with All-Day Power

Each W4 Plus earbud weighs 5.7 g and features a semi-in-ear design for extended comfort. The earbuds and charging case have a combined weight of 116.5 g. Each earbud provides more than three hours of continuous translation, while the charging case extends total translation time up to 12 hours and supports up to 18 hours of music playback.

Timekettle W4 Plus is available from September 6, 2026, through Timekettle's official website and Amazon. The full-feature version is priced at $379, while the W4 Plus Subscription Version is priced at $299.
