2. Translation Modes

The BL02 earbuds offer three distinct translation modes:

• Touch Mode: Two people each wear a headset. Click or double-click the earbud to initiate real-time translation. This mode is suitable for close acquaintances.
• External Mode: One person wears a headset, and the other person holds the cell phone. This mode is ideal for interactions with strangers where sharing an earbud is not convenient.
• Free Talk Mode: Both individuals wear a headset, allowing for continuous real-time translation without manual input, freeing your hands.

3. Binaural Fingerprint Control

The earbuds feature touch controls for various functions. A simple touch on the headset allows you to manage calls, control music playback (e.g., cutting songs), and activate translation features. This eliminates the need for physical buttons, providing a seamless user experience.
