Frequently Asked Questions (FAQ)

  • My earphones are connected via Bluetooth but I can't connect them with the EarJoy app. How do I do it?
    On some phone models, you need to pair the device directly through the app. If you paired the earphones through Settings > Bluetooth, remove the OpenVoice headphones from the list of paired items and complete the pairing process through the EarJoy app.

  • How do I reset the earbuds? Disconnect the earbuds from any Bluetooth sound source, place them in your ears, and press the touch control on both earbuds simultaneously 10 times quickly. You'll hear a "beep" sound, and they'll automatically turn off. Insert them into the charging case and take them out again to reconnect via Bluetooth.
