but the 360 does not have a headphone jack nor does it have rca and DVI does not carry sound it is video only so no matter if it has speakers or not it will not matter for the 360

and in theory you could plug both them in at the same time but i know on a slim it needs a bit of modding to remove some of the casing so both cables will fit and in the end he would need 3 cables to do the one job that the monitors i suggested that only cost him 10-15 more for a lot less wires

that is why i suggested getting hdmi unless they are going to use a head set or some other form for sound like using the digital out on the back of it to a supported device

if it was pc it would be a lot easier as even with DVI you could use motherboard or sound card for sound
