Use a Mac instead of an iPod as stereo system source

I think you're misinterpreting what you are seeing.

Since the impedance of the headphones doesn't change, the sound pressure level coming from the headphones is going to be proportional to the power that the signal source is producing. Is your iBook really a LOT louder than your iPod?

About your plug getting hot, the conductors in the plug are much bigger than the wires connecting the plug to the headphones, which in turn are much bigger than the wires that make up the voice coils in the headphones themselves. For the plug to be getting hot due to current passing, you'd have to be sending Amps through it, which would melt the wires (not to mention the voice coils in the headphones). I think it is more likely that the plug is just inserted into a hot iBook, and it is the heat from the CPU that is warming your plug.
