Under important must read notes:
"The IEM measurements coming up may be subject to change. I'm still working on a few things to refine the process. There is one important thing that folks should note: the FR graphs will not extend past 9kHz because that's the point where I feel the measurements will be misleading. The IEM measurement couplers tend to produce their own resonances and peaks between 9-14kHz. Such nonsensical information will not be posted because it only causes more harm than good. Heck, even the documentation on some of the commercial couplers state they are not accurate past a certain point."
Thanks for the clarification. However, on full sized headphones the measurements contain information above 9k and that caused the confusion.
