Operating Instructions
The Yanmis J66 earbuds offer three primary translation modes and intuitive touch controls for various functions.
Translation Modes
The earbuds support 144 languages for online translation. The translation speed is approximately 0.2 seconds.
- Touch Mode: Designed for two people, each wearing one earbud. Tap or double-tap the earbud to initiate real-time translation of spoken words. This mode is ideal for direct conversations.
- Outgoing Mode: One person wears an earbud, and the other person speaks into the phone. The earbud wearer hears the translation, and their speech is translated and played through the phone's speaker.
- Voice Mode: One earbud is used by two people. This mode allows for shared listening and translation in a single earbud setup.
