Maintenance

Cleaning

Regularly clean your earbuds and charging case to ensure optimal performance and hygiene. Use a soft, dry, lint-free cloth. Do not use abrasive cleaners or submerge the devices in liquid.

Storage

When not in use, store the earbuds in their charging case to protect them from dust and damage. Store the case in a cool, dry place away from direct sunlight and extreme temperatures.

Water Resistance (IP7)

The Jxrev W90 earbuds are IP7 waterproof, meaning they are protected against immersion in water up to 1 meter for up to 30 minutes. This makes them suitable for sports and outdoor activities, protecting against sweat and raindrops. However, they are not designed for swimming or prolonged submersion. Ensure the earbuds are dry before placing them back in the charging case to prevent damage.

Troubleshooting

Earbuds Not Pairing

  • Ensure both earbuds are charged.
  • Place both earbuds back into the charging case, close the lid, and then open it again to reset.
  • Turn off and on your device's Bluetooth.

Only One Earbud Working

  • Ensure both earbuds are charged.
  • Place both earbuds back into the charging case, close the lid, and then open it again. This should force them to reconnect to each other.
  • If the issue persists, try resetting the earbuds by forgetting them from your device's Bluetooth settings and re-pairing.

Low Volume or Poor Sound Quality

  • Adjust the volume on both your device and using the earbud touch controls.
  • Ensure the earbuds are properly seated in your ears and you are using the correct size eartips for a good seal.
  • Clean any debris from the earbud speakers and eartips.
  • Ensure there are no obstructions between the earbuds and your connected device.

Charging Issues

  • Verify the Type-C charging cable is securely connected to both the case and the power source.
