The connection from the computer to the headphone unit is mini usb on the Fiio side and whatever your laptop has on that side. The connection on the speakers is a choice of either XLR or 1/4". I would suggest you use a splitter cable that takes the stereo heaphone output and splits it into two channels for the two speakers. Based on the pictures I see on the internet you can use 1/4" at both ends. You should be able to find everything you need at monoprice.
