Water Resistance: While the earbuds are waterproof, avoid submerging them in water or exposing them to high-pressure water jets. Dry them thoroughly if they get wet.

8. Troubleshooting

If you encounter any issues with your Sansui W7 ANC Earbuds, try the following troubleshooting steps:

Problem	Possible Solution
Earbuds not pairing/connecting	Ensure earbuds are charged. Place earbuds back in the case, close it, then open it again to re-enter pairing mode. Turn off and on Bluetooth on your device. Forget "Sansui W7" from your device's Bluetooth list and try pairing again. Ensure no other devices are actively connected to the earbuds.
No sound or low volume	Check the volume level on both your device and the earbuds. Ensure earbuds are properly seated in your ears. Clean any debris from the earbud speakers and ear tips. Reconnect the earbuds to your device.
ANC not working effectively	Ensure ANC mode is activated (long press right earbud). Adjust earbud fit and try different ear tip sizes for a better seal. Clean the microphones on the earbuds.
Earbuds not charging	Ensure the charging case is charged. Verify earbuds are correctly placed in the case and charging contacts are clean. Try a different USB-C cable and power adapter.
Call quality issues	Ensure earbuds are fully charged. Check for strong Bluetooth connection. Ensure microphones are not obstructed. Move to a quieter environment if ENC is struggling with extreme noise.

9. User Tips

Optimal Fit: Experiment with the included S/M/L ear tips to find the size that provides the best seal for both comfort and effective noise cancellation. A good seal is crucial for bass response and ANC performance.
Battery Management: For extended use, consider turning off ANC when not in a noisy environment to conserve battery life. Always return earbuds to the charging case when not in use.
