I would say try to get another pair of these to measure, maybe in some time I'll send my pair off for measruement and buy a second one because I do really like them that much.  Also, I am on my second set because the first set I bought from MP4Nation came, sounded really quite bad for a couple days, and then one of the drivers just exploded or something of the like.  It was that sound you get when your volume is turned way to high on a BA driver except for at all volume's.  Like a muttled digital sound where music was trying to fight through a wall.  Fortunately MP4nation replaced the set, and the second pair I got was WAY different and in a good way.  No driver mis-match to my ears, very clean and extended sound on both ends, and not in the way the graphs show on this thread.  I would guess quality control isn't the best based on my experience and this, but it's worth getting a good set because IMHO this challenges anything in the IEM world up to $300-400 if you like a neutralish sound with some extension on both ends and a slight upper mids treble tilt.
