Very little, if any vocal information is at 10k and above. Did you reference the spike in the measurements I linked to? This graph is excellent at showing where various instruments and vocals produce sounds across the spectrum: http://www.independentrecording.net/irn/resources/freqchart/main_display.htm
Lush vocals, like earsonics and westone, are typically due to elevation between 500hz and below 2k, compared to perhaps dips between 3k and 5k (the presence region). If you tried my eq and found vocals less lush, it's the added db's at 3k.
I eq'd 50hz down for the bass b/c that's where the measured peak is in this set. It's till rising at 100hz. I'll give an additiional reduction at 100hz this afternoon and see how I like it. Thanks for the suggestion!
In any case im using my note 2's neutron mp music app for the EQ changes.
Definitely some difference to the one ur using.
However I find the 3k spike to be pleasant but changes are not that significant on my pair.
I'm still fiddling with my neutron EQ, it's entirely just words and numbers, a graph is missing for correct interpretation on my part.
I have to add that I have the non-woven fabric mod on my ie800s all the while.
