The Zalman Theatre 6’s use three headphone jacks to provide six channels of sound. Each plug is clearly marked with F, R, or C for front, rear, and center, respectively. You will need a 5.1 channel sound card to get the full effects of the headphones, but they work on any of the three plugs if you wish to plug them up to a laptop or a computer with a 2-channel sound card. In this case, I would recommend using the center channel."
