Regularly clean your earbuds and charging case with a soft, dry, lint-free cloth. Do not use abrasive cleaners, alcohol, or chemical sprays. Avoid getting moisture into any openings.

2. Water Resistance (IPX4)

The earbuds are rated IPX4 water-resistant, meaning they are protected against splashing water from any direction. This makes them suitable for use during light rain, sweating, or accidental splashes. They are not designed for submersion in water or for use during swimming or showering.

The IPX4 rating protects your earbuds from light rain, splashes, and sweat.

Troubleshooting

If you encounter issues with your Nsiucion Wireless Sleep Earbuds, refer to the following common solutions:

• Earbuds not pairing: Ensure both earbuds are in the charging case, then open the lid to activate pairing mode. Make sure Bluetooth is enabled on your device and that the earbuds are selected. Try forgetting the device in your Bluetooth settings and re-pairing.
• No sound or low volume: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly seated in your ears to form a good seal. Confirm the earbuds are connected to your device.
• Charging issues: Verify the charging cable is securely connected to both the case and the power source. Check the LED display on the case for battery status. Clean the charging contacts on both the earbuds and the case.
• Uncomfortable fit: While designed for comfort, individual ear shapes vary. Experiment with different earbud positions to find the most comfortable and secure fit.
• Buzzing sound: Some users may experience a faint buzzing sound between songs or when no audio is playing. This can sometimes be resolved by ensuring a strong Bluetooth connection or by updating your device's audio drivers if applicable.
• Battery life shorter than expected: Ensure the earbuds and case are fully charged. High volume levels can reduce battery life.
