Here's one of the problems as I see it.
Namely... Is the EQ based on an accurate measurement? Headphones are notoriously difficult to measure, and garbage in, garbage out. These measurements were presumably all made with good intentions but are wildly different. Are Sonarworks' measurements right? How does one tell? I do 'like' the sound better- it opens up the highs (the 535 has a dark-ish presentation, somewhat like the Senn HD650) but ears and measurement apparatus can both be 'fooled' occasionally.also, my sE535's have the custom tips (which I wouldn't do again), which seems likely to be in disagreement with any of the stock tips in the high end.
Think I'm probably going to sell my 535's and get some Etymotics, which the Shures sound more like after the EQ anyway. Maybe its better to start with flat rather than flatten out something that isn't. Might turn up in Trading Post soon.
Judging from the response, it doesn't seem like there's much interest, but I thought I'd post the curves anyway.
