Headphone question

What does impedance mean when looking at the specs for headphones?

I have looked at several definitions that either contradict each other or just (for me anyway) don't make any sense? :confused:

impedance is just how hard headphones are to drive. E.g. an ipod can easily drive a pair of grado's as they are 32ohm, but senns are a few millions squillion ohms so don't sound great with an ipod unless hooked up to a portable amp....

Im not that knowledgeable so wait for a proper reply

So the higher the Impedance the harder to drive, therefore more voltage/current is required to "get the best out of" a pair of headphones.....is that it in a nutshell?

using V=IR that would be true, but im not 100% sure.

All i know is that with a decent amp, better models in the grado/ senn range absolutely sing
