What would be some good portable headphones with the other things OP asked about?

Hey guys,   I've been lurking around for a while, just getting acquainted with all of this audiophile stuff. I'm trying to step up to more serious headphones that I can also use outside, and I was kinda thinking of the Fischer FA-006 after reading LFF's reviews, while stumbling onto the...

I wanted to know how the FA-004 compares to the FA-006 amped, SQ, bass quantity, comfort, etc.? I was planning to get the FA-006, but I want to make sure I know which one I would actually prefer.   BTW: I read both threads, but I didn't see enough to figure out which would be better for me...

If it remains that the only place that I can buy Fischer headphones is Frogbeats for decent and guaranteed fast shipping, then I suppose I'll just go for the FA-006. They're good enough for me, coming from the Nuforce NE-700M I'd assume.
