Besides impedence, the efficiency of the cans also matters in terms of where a player can drive the cans or not right? Starushz, If you get the senn, burn in for some time before they really open up. I was slightly dissapointed at the PX200 initially but now that they have opened up quite a bit, it's actually very decent for it's size and price. PX100 is open design though.
