5. Operating Modes
The LX80 AI Translation Earbuds offer multiple modes to suit various communication scenarios:

Figure 5.1: The LX80 offers four distinct operating modes for diverse scenarios.
- Speaker Mode: One person speaks into the phone, and the translation is played through the earbuds for the listener, or vice-versa. Ideal for one-on-one conversations.
- Offline Mode: Allows translation without an internet connection for pre-downloaded language packs. Useful for travel in areas with limited connectivity.
- Touch Mode: Users tap the earbud to initiate speech, and the translation is delivered. This provides controlled, turn-based communication.
