I also have a pair of 600 Ohm DT880s.
I can use them with my little FiiO E17 headphone amp, but I need to turn the volume up.
I guess you need to turn the volume fairly high on the laptop to use your DT880s?
As a rule of thumb, you need to turn the volume up higher with the 600 Ohm versions and turn the volume down lower with the 32 Ohm versions.
This is because the 600 Ohm versions need a bit more voltage (but a bit less current)
And the 32 Ohm versions need a bit less voltage and a bit more current to drive.
When we turn the volume up and down we are actually increasing and decreasing the amount of voltage outputted by the headphone amp.
Current is proportional to impedance, the higher the impedance the lower the current required by the phones.
The lower the impedance, the more current required by the phones.
But current is also proportional to voltage, as we turn the volume up, either phones will pull more current.
BTW, I've also tried my 600 Ohm DT880s with my iPad.
The volume never gets too loud, but the 'phones sound good with an iPad.
I certainly wouldn't recommend buying 600 Ohm 'phones for an IPad, but they do work.
Truth is, I wouldn't buy good headphones for an iPod or iPad anyway!
