You;re just cracking me up. The ety er4s is just the epytomy of analytical sound. I don't know how all those spikes in the mids and the highs got in your brain and what made you think that an iem has to have peaks in the mids and the highs to be analytical. Frankly, if the b2 is midcentric then my Vsonic GR02 Bass is analytical - its mids are laid back, the highs are extended and somewhat agressive, the treble extension is really good - it has to be analytical.
I found more of a V in it rather than analytical. It's signature was similar to the W4 with a little more treble energy (which leads to some sibilance). I would never call the W4 analytical, balanced, yes. Analytical, no. Neither are in my eyes as I still classify both of these as balanced.
emmmmm agreed er4s are basically the bassline for what i would consider analytical. But i just dont find the B2's even close in this regard to my pfe let alone the ER4S sure the B2 are revealing but not to the extent i thought they would be (IMO), i just find the sound out them weird. Its something about the low mids to bass region that just doesn't sound right to me cant quite put my finger on it though. (Now im not calling them junk or anything, just not to my taste).
I haven't heard the ER4, so I can't comment on that. All Etymotics I've owned I consider analytical by far (EtyKids and HF2). I agree with you on your thoughts about the B2 being classified as analytical as the midrange doesn't have the classic analytical sound to them.
In all honesty, I think it really depends on where you draw the line between analytical and balanced here. Also the way a person defines it on their own and interprets the definition will make the difference. Remember, a definition isn't set in stone, most still require some interpretation. The line isn't solid and black; on the contrary, it's grey and fuzzy.
