3.2 Modos de traducción
The JR04 earbuds offer three distinct translation modes to suit various communication needs:
- Modo de control táctil: Designed for close interactions. Each person wears one earbud. A single or double-click on the earbud initiates real-time translation. This mode is ideal for conversations with acquaintances.

- Modo de conversación: Both individuals wear an earbud, allowing for hands-free, real-time translation and communication. This mode is designed for fluid, continuous conversation.
