For the headphones you have, the E07K and E11 (amplifier wise) should be about equal sound quality wise.
As the laptop can use the E07K's DAC feature (USB) and the E11 does not come with a DAC at all.
And both the E07K and E11's amplifier can be used with the iPod.
It seems the E07K is the better choice.
