4. Operating Instructions

4.1 Intelligent Translation Modes

The K19 earbuds offer three primary translation modes via the "ear dance" app:

• Free Talk Mode: Ideal for natural conversations between two people. Each person wears an earbud, and the app facilitates real-time translation of spoken words.
• Translation Machine Mode: Suitable for one-on-one interactions where one person speaks into the phone/earbud, and the translation is played through the other earbud or phone speaker.
• Headphones + Phone Mode: Allows one person to wear the earbuds for listening to translations, while the other person speaks into the phone, and the translation is heard by the earbud wearer.

The earbuds support 134 languages with real-time translation, achieving high accuracy in approximately 0.3 seconds.

4.2 Audio Playback and Calls

Beyond translation, the K19 earbuds function as standard wireless headphones for music and phone calls.

• Music Playback: Once paired via Bluetooth, you can stream audio from your device.
• Phone Calls: Answer, end, or reject calls using the earbud controls (refer to the app or product instructions for specific touch controls).
