WTF is up with the bass?  Does it really sound like that?

In my very short experience with them, yes.

With certain headphones, I'm starting a new trend of just taking measurements and not bothering to listen to them. I did listen to them for a few seconds, and my only thought was "odd". I've since erased all other memories of that occasion.

Yeah, these graphs look about right. The ridges at 5K and 10K bothered me over time. I was used to them, so Grados weren't that bad to me when I first got into this hobby.

These were my daily headphones for about 3 years while I was in college. Once I got into other headphones I stopped listening to these. I busted them out for an evening a couple of months ago, and my reaction was like purrins -- "odd".

Looks like Diffuse Field gone wrong.

I remember them sounding thin and bright and there was other weirdness too but I coudn't get too flowery without another listen. 

It seems that a dip around 200hz or a bit higher is responsible for a lack of warmth in a lot of phones.

So why is that dip twice as much as on Tyll's HATS?

I'd doubt it's sample variation since the the V6 an 7506 are so close.

Maybe Sony changed the V6 at some point to be exactly the 7506? Tyll's V6 and the unit I measured look like totally different headphones. I know the measurement methods are different, but everything else looks different too.

Shouldn't you and Tyll show similar results below the upper midrange or midrange?  I was under the impression that you both have the same "ideal curve" ie flat until the upper mids, where he has an ideal curve and your ideal is still flat
