Thank you very much for you help!!
As long as your using a decent amplifier to drive your headphones, might as well just get the cheaper 250-Ohm headphones.
If you bought the 40-Ohm Audio Technica ATH-AD900X (open) headphones, you should be able to use them plugged directly into the iPod and iPad (using the E18 would be optional).
So you could just leave the E18 plugged into your desktop.
