If your speaker begins to buzz or Hum loudly it is a result of the speaker becoming frozen just as a computer or phone would.
All that is needed is a quick reset to bring the speaker working back to normal.
Reset the speaker by holding down both the Bluetooth button and the "O" button at the top of the speaker for 15 sec. Once the buzzing stops please turn the speaker back on to ensure it is working perfectly.
