Troubleshooting 

Cell phone does not detect the SX-918 

Solutions: 

1.

 

Confirm that the wireless earphone is turned on and in pairing mode. If the blue 
and red LEDs are flashing alternately, the earphones are in pairing mode. 

2.

 

If the wireless earphones are turned on but still can't be found on your Bluetooth 
device, restart both the cell phone and the wireless earphones and then try again. 
 

After connecting the wireless earphone with your mobile phone, you experience 
disconnections or low sound quality. 

Solutions: 

1.

 

The wireless earphones may have low battery. Recharge the device as needed. 

2.

 

There may be an obstacle between your cell phone and the wireless earphone. 
Ensure this is not the case. You should be aware that your hand may obstruct 
communication if you are holding it against the SX-918. Make sure the line of 
communication is clear of any obstruction between these two devices. 

3.

 

Your wireless earphone may be out of range. Try moving it closer to your cell 
phone for best results. 
 

The wireless earphone has connected successfully, but you can't listen to music. 

Solutions: 

1.

 

Some cell phones do not have a complete Bluetooth function and stereo 
Bluetooth module that are required to listen to music. Please test whether this is 
the case by connecting your wireless earphone with another cell phone. If you 
can listen to music through the other cell phone, the wireless earphone is 
functioning as it should. 

2.

 

Check your Bluetooth settings of handsfree mode. 
 

How do you use the wireless earphone to listen to music or chat on computer? 

Solution: 

If your computer has a Bluetooth function, simply open it and search for the 
wireless earphones (SX-918). If your computer does not have a Bluetooth 
function, then you will need a wireless adapter in order to connect your computer 
to the SX-918. We recommend IVT wireless adapters.
