power handling capacity in Sony headphone models

[luv2liv]

what does power handling capacity means in Sony headphones? i was comparing between the different models. the different categories are:
magnet type | sensitivity | power handling.
what should i be looking for in these categories for good sound with the Sony models?

I generally look for high sensitivity, and driver size(>30mm) when selecting headphones. Power handling is not too big of an issue, as most music sources have low power output anyway for headphones. I like the way Sony's sounds also, they're about the only brand of headphones I buy. The driver size IMO affects the depth of Bass reproduced(i.e.-larger is better).
