I also didn't find anything wrong with the title. as much as i will read and learn about impedance and sensetivity i will never figuere it out completely...I am just stupid i guess
at first i though that it is related only to impedance...the highest the harder to drive. but than i read in head fi that also low impedance are hard to drive (i also saw the formula) usually the ones with the low sensetivity too.
most of the grado models have impedance value of 32ohm (pretty low) and sensetivity value of 98db which is also considered very low in the headphone world. so what is the logic about them being very easy to drive? they always say that low impedance are hard to drive and need a lot of power, now i guess that they usually means those with the rather low sensetivity as well. 98db is one of the lowest sensetivity rating i ever seen in headphones, so why are the grado easy to drive than...why more than the sennheisers?
this is probably for the sound science forum but if we are already discussing this i brought it up.
