Abstract: A combining housing has first, second and third connectors. A music player has a first line adapted to be coupled to the first connector. A special effects box has a second line adapted to be coupled to the second connector. Earphones have a third line adapted to be coupled to the third connector. A musical instrument has a supplemental line adapted to be coupled to the special effects box. Positive, negative and ground wires are within each of the lines and continue within the combining housing. An electrical assembly includes the positive, negative and ground wires. The positive lines are coupled together within the combining housing forming a first junction. The negative wires are coupled together within the combining housing forming a second junction. The ground wires are coupled together within the housing forming a third junction.
