Now, I've had the 598's for 2 years and, while it was definately not a bad choice for my first full sized headphones, I feel that I can find something that suits my tastes a little better.
What I what in comparison to the 598:
More intimate sound/less laid-back sound.
Less muddyness/more airness
A brighter sound signature.
There is one point that I completely disagree with most people in here: i do not feel that they lack bass in any way, in fact they have a bit more than what I'd like.
I've noticed that the bass increases quite a bit when using with my Xonar DX, when connected to onboard sound or my ClipZip, I do feel that it does lack bass.
Perhaps all I need is sidegrade.
Judging from my IEM choices, I seem to prefer the vocals a bit forward.
PS: For reference, my favourite IEM are the Hippo Shroom EB and Hifiman RE-400
