【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

[Stress-free interpretation even in noisy environments] The W4 is equipped with bone conduction microphone technology. By physically extracting the speaker's voice from the vibration of the bones in the ear, it is less affected by ambient noise such as conversations and machine sounds. While conventional air conduction microphones pick up ambient noise along with the voice, causing translation errors, the W4's bone conduction sensor accurately isolates only the speaker's own voice. This enables clear interpretation even in factory settings, crowded exhibitions, and outdoors, freeing you from the stress of having to ask people to repeat themselves in business situations. This is an innovation of the W4 that was not possible with conventional technology.
[Supports 52 Languages and 106 Accurate Accuracy, Including Indian English and Southeast Asian Accents] In addition to 52 languages, W4 supports 106 different accents, including Indian English, Singaporean English, and Vietnamese. Its high-precision accent recognition enables smooth communication even when the other party is not a native English speaker. Furthermore, it features 13 offline language pairs, providing stable translation even in locations with unstable internet connections, such as factory visits or business trips to regional cities. From technical meetings with overseas suppliers and negotiations with local agents to project meetings with multinational teams—W4 is a powerful partner that lowers language barriers and ensures smooth business operations in any global setting.
[Two-Person Conversation Mode and Listening Mode: Choose the Optimal Translation Style for Each Situation] The W4 comes standard with two translation modes that can be simply by downloading the dedicated app and connecting via Bluetooth. In "Conversation Mode," once both parties have set their languages in the app, the translated audio will play as soon as the other person finishes speaking. This enables natural back-and-forth conversations, from business negotiations and meetings to exchanging business cards at trade shows and lunch meetings. The other mode, "Listening Mode (Observation Mode)," is ideal for one-way information gathering situations such as speeches, presentations, seminars, and factory tours, allowing you to catch important information without interrupting or disturbing others. It is also useful for keynote speeches at international conferences, lectures by local staff, and as a substitute for simultaneous interpretation in online meetings. By using these two modes appropriately, one device can cover all business situations, from two-way conversations to one-way information gathering.
[Equipped with "Babel OS 2.0," eliminating the stress of waiting] The W4 is equipped with our proprietary, cutting-edge AI translation engine, "Babel OS 2.0," and uses streaming translation technology to minimize response delays to an industry-leading level. Instead of "speak → wait → reply," it enables natural conversational exchanges as if you were speaking your native language. This overwhelming response speed and smooth experience are the core strengths of the W4, made possible only by our many years of voice processing technology and AI research. It truly shines in situations where timing is critical, such as business negotiations and discussions.
[4 hours on a single charge, up to 12 hours with the charging case, and offline mode for peace of mind on business trips] The W4 offers 4 hours of continuous use on a single charge, and up to 12 hours with the charging case. It can easily cover a full day's business schedule, from morning meetings and business negotiations to factory tours, lunch meetings, and evening meetings. It also features an offline mode that can be in environments without a signal. The translation function works even in places without a network, such as on airplanes, in factories in regional cities, and underground facilities, and it supports USB-C fast charging. You can quickly recharge it during short waiting times at airports.
[W4 New Features Added, Unlimited Plan for Even Smoother Translation] In addition to "Two-Person Conversation Mode" and "Listening Mode," W4 now includes "Voice/Video Translation," "Call Translation," and "AI Real-Time Summarization." We offer a subscription service that allows you to use the improved W4, enhanced by OTA updates, even more conveniently.
