6.2 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.
6.3 Water Resistance
The earbuds are rated IPX4 water resistant, meaning they are protected against splashing water from any direction. This makes them suitable for workouts and light rain. However, they are not designed for swimming, showering, or submersion in water. Do not expose them to saltwater or other liquids. Ensure the earbuds are dry before placing them back in the charging case to prevent damage.

7. Troubleshooting
- Earbuds not pairing: Ensure earbuds are charged, Bluetooth is enabled on your device, and the earbuds are in pairing mode. Try resetting the earbuds by placing them back in the case, closing the lid, and then reopening it.
- No sound from one earbud: Check if both earbuds are charged. Try re-pairing them with your device. Sometimes, placing both earbuds back in the case and taking them out again can re-sync them.
- Low volume: Adjust the volume on both your device and the earbuds. Ensure the earbud tips are properly sealed in your ear canal.
- Charging issues: Ensure the charging cable is securely connected and the power source is working. Clean the charging contacts on both the earbuds and the case.
