Water Resistance
The JBL Tune 115TWS earbuds are rated as Water Resistant. This means they can withstand light splashes of water, such as sweat or light rain. They are not designed for submersion in water or for use during swimming. Always ensure the earbuds are dry before placing them back into the charging case to prevent damage.
Troubleshooting
If you encounter issues with your JBL Tune 115TWS headphones, try the following solutions:
- No Sound or Poor Sound Quality: Ensure the earbuds are properly seated in your ears and that you are using the correct size ear tips. An improper fit can significantly affect sound quality, especially bass. Try resetting the earbuds by placing them in the charging case and closing the lid, then reopening.
- Earbuds Disconnecting or Unstable Connection: Ensure your device's Bluetooth is enabled and the earbuds are within range. If the connection is unstable, try unpairing and re-pairing the earbuds with your device.
- One Earbud Not Working: Check if the non-working earbud is charged. Place both earbuds in the charging case, close the lid, and then reopen to re-establish connection.
- Earbuds Continue Playing After Removal: The earbuds do not have an auto-pause feature when removed from the ear. You must manually pause playback or place them back in the charging case to stop audio.
- Charging Issues: Ensure the charging cable is securely connected to both the case and the power source. Clean the charging contacts on both the earbuds and inside the case with a dry cotton swab to remove any dust or debris.
