what differences do you hear ?

the grado hp-2 and grado rs-1 have different ways with music;;;addthe equally popular senns 650 and they're strengths and weaknesses are even more sharply defined!
would like you guys and gals who have had actual experience with two or all three of these cans to state what you notice and then rate them 1.2.3.
thanks for your imput and help...
