You can get the Zx version for about $10 more ($105 vs $95) which comes with the external headphone unit. That has the headphone jacks, volume knob and microphone built into it which is pretty handy. You don't have to use it.
*The external unit is much handier than trying to connect headphones to the rear of your PC. Some speaker have headphone jacks but the speakers have to be left on for that to work, plus you're using an additional amplifier which may distort the sound slightly.
