🔹 Product Description

Timekettle W4 Pro AI Translator Earbuds – Bidirectional Real-Time Translation in 40 Languages with Voice Call Support

The Timekettle W4 Pro fundamentally changes how multilingual conversations feel in practice. Unlike traditional translation apps that require awkward phone passing or turn-taking, these earbuds deliver true bidirectional simultaneous interpretation – both parties speak freely while translations flow naturally through the earbuds .

Why the W4 Pro is different

Most translator devices interrupt conversations. You speak, pause, wait for translation, then the other person speaks. The W4 Pro eliminates this staccato rhythm. Using Timekettle's HybridComm technology and Babel OS, the system segments sentences and predicts their completion, enabling near-zero latency translations that feel like a real interpreter is whispering in your ear .

Three powerful translation modes for every scenario

👥 One-on-One Mode – Natural Face-to-Face Conversations
Share one earbud with your conversation partner. You speak your language; they speak theirs. The W4 Pro's triple microphone array with vector noise cancellation isolates only your voices, eliminating crosstalk even in close proximity . The open-ear design lets you maintain eye contact and hear ambient sounds naturally. Perfect for business meetings, client dinners, or travel conversations.

🎓 Listen & Play Mode – Multilingual Meetings & Presentations
Seamlessly switch between listening and speaking during multilingual meetings. Timekettle's AI Semantic Segmentation ensures rapid sentence parsing, while AI Memo automatically generates intelligent post-meeting summaries . Your audience hears translated speech through their devices – no additional equipment needed. Ideal for international conferences, lectures, or group discussions.

📞 Voice Call & Video Translation – Remote Communication
Take phone calls or join video conferences on Zoom, Teams, or any platform. The W4 Pro translates both sides of the conversation in real time – and the other party needs no special device or app, just their regular phone . Floating app windows provide live bilingual text transcriptions during calls, ensuring every word is captured .

🎬 Multi-media Translation – YouTube, Podcasts & Streaming
Watch foreign videos, listen to podcasts, or stream global content. The W4 Pro translates audio directly through your earbuds in real time – perfect for consuming international media without subtitles .

40 languages, 93 accents – truly global coverage

The W4 Pro supports 40 languages with 93 regional accents, covering most countries and territories worldwide . Key language families include:
