🔹 Product Description

Timekettle W4 Pro AI Interpreter Earbuds – Bidirectional Simultaneous Translation for Meetings, Travel & Business

The Timekettle W4 Pro is not just another translator device — it's the world's first AI interpreter earbud to offer true two-way simultaneous translation . Unlike traditional translation apps that require awkward phone passing or turn-taking, the W4 Pro allows both parties to speak freely while translations flow naturally through the earbuds in real time .

Conversations That Feel Natural, Not Like a Tech Demo

Most translator devices interrupt conversations. You speak, pause, wait for translation, then the other person speaks. The W4 Pro eliminates this staccato rhythm, delivering translations with near-zero latency so conversations flow as naturally as speaking your native language . Whether you're negotiating a business deal, traveling internationally, or video-calling overseas clients, the W4 Pro breaks language barriers without breaking conversational rhythm.

Three Powerful Translation Modes for Every Scenario

👥 One-on-One Mode (Simul Mode) – Share one earbud with your conversation partner. Both speak in their native languages; translations flow simultaneously through the earbuds. Perfect for business meetings, client dinners, or travel conversations where natural dialogue matters.

📱 Listen & Play Mode – Multilingual Meetings & Presentations – Host multilingual meetings effortlessly. Speak while others listen to translated speech through their devices. AI automatically segments long speeches, highlights key content, and generates meeting summaries for easy follow-up. Perfect for international conferences, round-table discussions, or classroom lectures .

📞 Voice Call & Video Translation – 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—just their regular phone . Floating bilingual text transcriptions ensure every word is captured.

🎬 Media Translation – YouTube, Podcasts & Streaming – Watch foreign YouTube videos, listen to podcasts, or stream international content. The W4 Pro translates audio directly through your earbuds in real time—no subtitles needed. Includes 300 minutes of free monthly media translation .

40 Languages, 93 Regional Accents – True Global Coverage

The W4 Pro supports 40 languages with 93 regional accents, covering 85% of the world's population . Key supported languages include:

• Asian languages – Mandarin (Simplified/Traditional/Taiwanese), Cantonese, Japanese, Korean, Thai, Vietnamese (Northern/Southern)

• European languages – English (8 accents), French (2 accents), German, Spanish (20+ accents), Italian, Portuguese (Brazilian/European), Russian

• Other languages – Arabic (MSA/Egyptian/Levantine/Gulf), Hebrew, Hindi, Urdu, Tamil, Bengali, Indonesian, Malay, Turkish, and more 

Offline Translation – No Internet? No Problem

Download offline language packs before your trip. The W4 Pro supports 13 offline language pairs across 8 core languages, including English ↔ Chinese, Japanese, Korean, French, Spanish, Russian, and German . Perfect for airplanes, subways, remote hiking trails, or anywhere internet is unavailable. No subscription required—lifetime free updates included .

Triple Microphone Vector Noise Cancellation – Clear in Any Environment

The W4 Pro features a triple microphone array with advanced vector noise reduction technology. This system isolates only your voice, eliminating side conversations even when multiple people speak in close proximity . Unlike standard earbuds that struggle in noisy environments, the W4 Pro ensures translation accuracy even in busy airports, crowded cafes, or trade show floors .
