Sony MDR 7509s

[TheBoss]

I'm kinda new here.

I wonder if someone already tested SONY MDR 7509 to see if this has flat response curve as my older 7506 (on a graph).

how do these compare to the V6/7506 in regards to portable use with a Cowon D2 MP3 Player?
24ohm vs 63 ohm - but what does that mean for me? easier to drive but what else? (noob

)
