It really depend on what equipment (Amp and/or DAC-Amp). the other suggeswtion is to get several cable each with different plug consider the cable on HD650 is detachable, I have HD600 and I made cables of my own using both 6.3mm and 3.5mm. I didn't make XLR because I don't have equipment using XLR connector. so it is depend upon what connector of your signal come from.
