6. Maintenance

To ensure the longevity and optimal performance of your SANSUI W28 earbuds, follow these maintenance guidelines:

• Cleaning: Regularly clean the earbuds and charging case with a soft, dry, lint-free cloth. Do not use harsh chemicals or abrasive materials.
• Ear Tips: Remove and clean the silicone ear tips periodically with water and mild soap. Ensure they are completely dry before reattaching.
• Water Resistance: The earbuds are IPX4 waterproof, meaning they are resistant to splashes and sweat. Do not submerge them in water or expose them to heavy rain. Dry them thoroughly if they get wet.
• Storage: Store the earbuds in their charging case when not in use to protect them and keep them charged. Avoid extreme temperatures.

7. Troubleshooting

If you encounter any issues with your SANSUI W28 earbuds, please refer to the following common solutions:

• Earbuds not pairing: Ensure both earbuds are in the charging case and the lid is open. Check if Bluetooth is enabled on your device. Try resetting the earbuds (see below).
• Only one earbud working: Place both earbuds back into the charging case, close the lid, wait a few seconds, then open it again. This often re-syncs them.
• No sound: Check the volume level on both your device and the earbuds. Ensure the earbuds are properly connected to your device.
• Disconnection issues: Ensure the earbuds are within the Bluetooth range of your device. Avoid obstacles that might interfere with the signal.

Factory Reset

If issues persist, a factory reset can often resolve them:

1. Open the charging case lid.
2. Locate the small button inside the charging case (refer to the 'Key Operation' image in section 5.1).
3. Long-press this button for 5 seconds.
4. The external blue indicator light on the case will flash 5 times, and the earbuds will power off while disconnecting from Bluetooth.
