  • Insert the charging cord  into the charging port of the speaker.
  • Connect the power adapter to a power outlet.

Leave this charging for at least 3.5 hours then check if the issue still occurs.

Method 4: Device is not in range

In order for the Bluetooth connection to work properly the speaker and device it is connecting to should be not more than 100 feet away from each other. This range will decrease if there are a lot of obstructions or signal interferences such as walls between both devices.

Try placing the speaker and the device it is connecting to side by side then check if the problem still occurs.
