Key Features

• 40% More Accurate with Patented Bone-Voiceprint:Utilizing exclusive Bone-Voiceprint technology and dual-mic arrays, W4 captures your voice even in 100dB noise. It ensures reliable, high-clarity translation in challenging scenarios like airports, trade shows, and crowded cafes where ambient noise usually interferes.
• Seamless Interaction: Share and Listen Modes:Simply share a single earbud to enjoy a seamless, hands-free 1-on-1 conversation experience. Alternatively, enable “Listen & Play” mode to transform it into your personal interpreter, helping you navigate meetings with ease or take in the sights while traveling. These modes are designed to minimize reliance on your phone, allowing you to focus on natural face-to-face conversations during group gatherings or language learning sessions, fostering deep engagement and full immersion.
• AI Context Correction and Smart Applications: Leveraging our proprietary LLM (Large Language Model) technology, our companion app goes beyond literal meanings to accurately understand user intent, automatically correcting homophones and semantic errors, thereby reducing the time needed to clarify communication by 50%. Furthermore, the app boosts productivity through AI-driven meeting note generation and intelligent conversation features, ensuring you never miss any critical details during technical consultations or professional seminars.
• Travel the World with Confidence: Enjoy access to 52 major languages and 106 regional accents, empowering you to explore the world with total confidence. W4 is specially optimized for English, Spanish, French, German, Japanese, and Italian, ensuring your speech sounds as natural as a local’s—whether you’re in a business meeting in London or on the subway in Tokyo. Experience professional-grade translation services across more than 100 countries and regions, with more advanced features available to elevate your global communication.
• Multifunctional 3-in-1 with Smart Touch Controls: The W4 is a powerful “3-in-1” device designed to meet the needs of every lifestyle. Not only does it feature real-time AI translation, but it also serves as a high-fidelity music headset and a headset with crystal-clear call quality. With intuitive double-tap controls, you can easily manage music playback and calls; with just this one versatile device, you can seamlessly switch between business meetings, international calls, and your favorite music playlists.
• To ensure long-term comfort, the W4 features non-slip ear hooks that keep the earbuds securely in place and prevent them from falling out during daily commutes and other activities. We recommend taking a short break after 4 hours of continuous translation use or 6 hours of continuous music playback; this is the ideal time to place the earbuds in the charging case to recharge them (a full charge takes 1.5 hours, and combined with the charging case, the total battery life can reach 18 hours). Additionally, your personal data security is strictly safeguarded, with all privacy protection measures fully compliant with GDPR and FERPA regulations.
