Q1: Why does the music cut in and out sometimes?

A1: 1-Please make sure there is no obstacle between   
       the earbuds and your device.
       2-Please make sure there is no Microwave  oven/
       Wifi transmitter around you, which is more  likely 
      to produce electromagnetic interference and result 
       in a signal interruption.

Note: 

Please keep the device and the earbuds as close 

           as possible to ensure a more stable Bluetooth 
           connection.

Q2: Why I can't get the earbuds charged?

A2: 1-You need to remove the plastic protector on the
       earbuds charging point first.
       2-Make sure the charging case was fully charged.
      3-Or make sure the charging case was plugged 
      into the power supply.
