OK HERE IT GOES> First off, don’t get those sennheiser headphones, for around that price you can get my headphones which are American Audio HP700, the Numark RedWave and the Allen & Heath XD40. The Mixtrack, lacks a soundcard, the Mixtrack Pro comes with a built in soundcard, there are other differences but mostly insignificant, they are almost the same. When you mix, you need to cue up a song in your headphones while another plays through your speakers, that’s what the soundcard is all about, it allows you to connect your headphones and speakers so they play a song through one, and cue another song through your headphones, I believe that’s the function from what I understand, if not let somebody else correct me on this.
