Yes, the impedance of the headphones makes a difference in the volume. The lower the impedance, the greater the volume. It's interesting that some of the high-end headphone interfaces like my Grace m900 prefer higher impedance cans, which I use, sort-of. My Beyerdynamic DT 770 Pro are 250 ohms, not at all high but high enough that some headphone amps won't give enough volume.
