A:AnswerIt has a 3.5mm jack on the cord if that's what you mean by aux cord, which is standard size for aux cords and aux input.

A:AnswerThe main difference so far that I can tell is that the lite can be used on pc,Mac, and gaming consoles. The regular kraken can only be used on pc, and mac. Both are pretty much the same overall.
A:AnswerIt doesn't have a USB plug. It plugs into a 3.5 mm audio + mic jack. But it also has a splitter so that the stereo and mic can be plugged in separately if needed.
