i have the ex70 and 280pro. i want the er4, but its so spendy, and when i tried it it was very uncomfortable, and the foamies didnt stay very well, etc... and not quite as portable as the er6. the er6 would fit in my budget, perfectly portable, isolates really good, etc... but doesnt sound up to par as er4. and the bass wasnt all that great when i tried them... the Beyer 770... i havent heard it but i have heard it is the king of bass.... and its closed, but i dont know how it compares to my 280pros in isolation. i know its 250 ohm, so would my AH be a very good amp for it?


above all:

1/2 - deep, tight, well defined bass
2/1 - portability
3 - isolation
4 - everything else


any other recommendations???
