Once I received my headset and read the instructions, I proceeded to charge it using the charger that came with it. After 30 minutes of charging I heard a slight "pop" sound that came from the charger's plug. I quickly noticed that the light on the headset showing that charging was taking place, had gone out.  I didn't smell any smoke thankfully and I checked to ensure my wall receptacle socket was alright. No problems at my wall socket, I plugged in other items to ensure all was well with my wall socket.
