In that case, it depends on the difference in efficiency versus impedance ratings between headphones. Recently, I have run across some very-low-impedance headphones that have very low efficiency ratings (and thus relatively low sensitivity ratings) - and those turned out to give me the shortest battery life from a portable device out of all of the headphones that I have tested.
That exception aside, if you turn up the volume of some higher-impedance headphones to nearly double the volume-control setting as opposed to a given lower-impedance headphone, then yes, those particular higher-impedance headphones will suck more battery time away from a portable device. Remember, it's efficiency, not impedance, that will directly influence the battery life at a given perceived loudness level.
