Setup Guide
1. Initial Charging
Before first use, fully charge the earbuds and the charging case. Connect the provided USB charging cable to the charging case and a power source. The indicator lights on the case will show charging status.
2. App Download and Authorization
The translation functionality relies on the "Ear Dance" application. Download the app from the App Store (iOS) or Google Play Store (Android). After installation, open the app and enter the Authorization Code found on the included color card to bind your device and activate full features.
3. Bluetooth Pairing
Ensure your phone's Bluetooth is enabled. Take the earbuds out of the charging case. They will automatically enter pairing mode. On your phone's Bluetooth settings, select "T209" to connect. Once connected, the earbuds are ready for use.
Operating Modes
The YISUN AI Translation Earbuds offer five distinct translation modes via the "Ear Dance" app, catering to various communication needs:
1. Free Talk (Dual-Ear) Mode
This mode is designed for two individuals, each wearing one earbud, to engage in real-time translated conversations. Both parties can speak naturally, and the translation will be delivered to the other person's earbud.
2. Headphone + Phone Mode
One person wears the earbuds, while the other speaks into the mobile phone. This is suitable for situations where sharing earbuds is not convenient, such as quick interactions with strangers.
3. Voice Note Mode
Record voice notes and have them translated into your desired language. This mode is useful for transcribing spoken thoughts or lectures into text in another language.
4. Photo Translation Mode
Utilize your phone's camera to translate text from images, documents, or signs. Simply take a picture within the app, and it will translate the detected text.
5. Translation Machine Mode
Similar to a traditional translation device, both users interact with the app on their respective phones. Each person speaks into their phone, and the translation is displayed on the screen and can be played aloud.
6. AI Chat Mode
Engage in conversations with an AI robot for information retrieval or practice. You can ask questions in your language, and the AI will respond in the selected target language, providing both text and audio output.
