The JOYWISE T12 earbuds provide approximately 8 hours of continuous playback on a single charge (at 50%-60% volume). The compact charging case offers multiple recharges, extending the total listening time to up to 42 hours. This ensures you can enjoy your audio throughout the day without frequent recharging.
Maintenance
Water Resistance (IPX6)
The earbuds are rated IPX6 waterproof, meaning they are resistant to high-pressure water jets from any direction. This makes them suitable for workouts and outdoor activities where they might be exposed to sweat or light rain. However, they are not designed for submersion in water.
Cleaning
To maintain optimal performance and hygiene, regularly clean your earbuds and charging case. Use a soft, dry, lint-free cloth to wipe away any dust or debris. For stubborn dirt, a slightly damp cloth can be used, but ensure the earbuds are completely dry before placing them back in the charging case or using them.
Troubleshooting
- Earbuds not pairing:
Ensure both earbuds are charged. Place them back in the charging case, close the lid, then open it again to re-initiate pairing mode. Check your device's Bluetooth settings and try reconnecting. - Only one earbud working:
Ensure both earbuds are charged. Place both earbuds back in the charging case, close the lid, and then open it again. This often resets the connection between the two earbuds. If the issue persists, try re-pairing them with your device. - Poor sound quality or disconnections:
Ensure your device is within the 10-meter Bluetooth range and there are no significant obstacles between your device and the earbuds. Try disconnecting and re-pairing the earbuds. - Earbuds not charging:
Verify that the protective film has been removed from the charging contacts on the earbuds. Ensure the charging cable is securely connected to both the case and the power source. Check if the charging case itself has power. - Buttons not responding:
Ensure the earbuds are powered on and connected to your device. A simple restart (placing them in the case and taking them out) can often resolve minor control issues.
