5. Operating Modes and Functions
The earbuds offer various modes to suit different communication needs.

5.1 Real-Time Translation
The core function of these earbuds is real-time language translation, supporting 144 languages and accents with a response time as fast as 0.25 seconds.

5.1.1 Silent Mode
In Silent Mode, the earbuds translate spoken language and display the text on your connected device's screen, allowing for discreet communication.
5.1.2 Earbud Mode
This mode is ideal for one-on-one conversations. One person speaks into the phone, and the translation is played through the other person's earbud. Alternatively, both users wear an earbud, and the translation is heard directly.
5.1.3 Speaker Mode
Speaker Mode allows you to speak into your phone, and the translation is broadcast through your phone's speaker, suitable for communicating with a group or when you don't want to share an earbud.
5.1.4 Binaural Mode
Both earbuds are worn by a single user. This mode is suitable for listening to translated audio from a speaker or for personal language learning.

5.2 Call Translation
The earbuds can translate conversations during phone calls, enabling communication across language barriers directly through your calls.
5.3 Multimedia Playback
Beyond translation, the earbuds function as standard wireless headphones, providing high-fidelity audio for music, podcasts, and other media. They feature 14.2mm dynamic speakers for clear sound and impactful bass.
