Are the Hfi-550 and hfi-650 equally hard to drive from a portable? i mean will they sound eqally loud at the same volume from my portable?

The HFI700's are very easy to drive. I use them on the absolutely lowest volume possible out of my audigy2 and also on the lowest out of my portable, which can be a little too loud, depending on the mp3s volume.
