How to Pair Your Earphones with Your Phone

Follow these steps to pair your YT18 earphones:

1. Ensure both the earbuds and the charging case are fully charged before first use.
2. Take both earbuds out of the charging case. They will power on and start pairing automatically. If not connected to your device for over 5 minutes, they will turn off. To manually turn them on, press the MFB button for about 3 seconds until you hear "Power on".
3. One earbud will flash a white light, while the other flashes white every three seconds, indicating successful pairing.
4. Enable Bluetooth on your phone, search for "YT18", and select it to connect. You should hear a voice prompt "Connected" when wearing the earbuds.
5. If the earbud indicator light is off, it means the phone is connected.

Automatic Connection: By default, the earbuds will automatically connect to the last paired phone when powered on.

Troubleshooting Pairing: If you encounter pairing issues, place the earbuds back into the charging case, close the lid, wait for 1 minute, then open the case and try reconnecting.

Single Earbud Use: These earbuds can be used individually. To use a single earbud, simply remove it from the case and connect it to your phone. To switch back to dual mode, turn off one earbud manually or place it back in the charging case.

Frequently Asked Questions

Q: Why won't my earbuds pair with my phone?

A: Ensure the earbuds are fully charged and powered on. Also, make sure your phone's Bluetooth is enabled. If problems persist, turn off the earbuds (5 quick clicks), place them in the charging case, close the lid, wait 1 minute, open the case, and reconnect.

Q: Why does the music cut in or out?

A: First, ensure the distance between your earbuds and phone is within 10 meters (without obstacles). If the distance is less than 10m, place the earbuds back in the case, close the lid, and forget "YT18" in your phone's Bluetooth settings. After 10 seconds, open the case and reconnect the earbuds to your phone.

Q: Why won't the earbuds charge or disconnect from the phone after placing them in the case and closing it?

A: Ensure the charging case has sufficient battery power. If the case's battery is low, the earbuds may not charge or disconnect. Use a Type-C cable to fully charge the case.

Q: Are these earbuds sweat- and water-resistant?

A: These earbuds are sweatproof and IPX7 waterproof. However, for electronics, it is not recommended to submerge them in water. They are not resistant to hot water, and water vapor can enter and damage the components.
