- On your device (smartphone, tablet, laptop), go to Bluetooth settings and enable Bluetooth.
- Look for "S42" in the list of available devices and select it to connect.

Maintenance
Cleaning
Regularly clean your earbuds and charging case to maintain optimal performance and hygiene.
- Use a soft, dry, lint-free cloth to wipe the earbuds and charging case.
- For ear tips, remove them from the earbuds and clean with a mild soap solution if necessary, then rinse thoroughly and dry completely before reattaching.
- Do not use abrasive cleaners, alcohol, or chemical solvents.
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 extreme temperatures.
Water Resistance (IPX7)
The earbuds are IPX7 waterproof, meaning they can withstand submersion in up to 1 meter of water for 30 minutes. This makes them resistant to sweat and rain. However, the charging case is not waterproof. Do not expose the charging case to water or moisture.
- Do not use the earbuds for swimming or showering.
- Ensure earbuds are completely dry before placing them back into the charging case to prevent damage.
Troubleshooting
Earbuds Not Pairing/Connecting
- Ensure both earbuds are charged and taken out of the case.
- Turn off and on your device's Bluetooth.
- Forget/delete "S42" from your device's Bluetooth list and try pairing again.
- If only one earbud connects, try placing both earbuds back in the case, closing the lid, waiting a few seconds, and then taking them out again.
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 and that the ear tips provide a good seal.
- Clean any debris from the earbud speaker mesh.
Charging Issues
- Ensure the USB-C cable is securely connected to both the case and the power source.
- Try a different USB-C cable or power adapter.
- Ensure the charging contacts on the earbuds and inside the case are clean and free of debris.
Poor Call Quality
- Ensure the microphone on the earbuds is not obstructed.
