oh , i got test with e5 before ...
bijou 3 + e5 , personally feel , mid bass overtake deep bass making it lost the "dup dup" bass already ... and improved in tremble part ... well , vocal wise is nice but somehow cover the background music.
So depend on ur sound preference , personally i miss the "dup dup" bass , so i am not satisfy with e5 =p

Sifu sekalian , wanted to ask is it ok to upgrade to im716 from bijou 3 ? =p
tempted by those rm200 im716 in forum

thx for the advise g3n0c|d3 , but i am not bass head anyway , rather i prefer deep bass somehow ... lol ... optional ...

hmmm , may b i miss my x3i a bit ... died on me last time after many time of getting split in half , *sad*
