Hi all,
Mostly for curiosity's sake, I'm considering getting some in-ear microphones that I've seen mentioned in several threads: SP-TFB-2. However, in those posts, I see several mentions that these are good for "relative" and not "absolute" measurements. And also, implications that responses at higher frequencies should be ignored. For example, these posts:

I'm most interested in comparing the general shape of the FR curve between headphones. Also to see what effect, if any, various EQ's have on the curve. I don't care so much whether the absolute volumes at given frequencies are the same between headphones. Are these microphones good enough to give a rough picture of the curve?
Also, in the second post it mentions that only the LF curves (e.g. below 800 Hz) are valid. The mics are supposedly flat from 20Hz to 20KHz. Why are measurements at higher frequencies less accurate or not valid? Is this due to the wavelengths and geometry of the ear?
Thanks!

Dan Clark Stealth Review (State of the Art Headphone)
I'm staring at these photos, staring at my Stealth, looking back at the photos, but I don't understand what you're looking at? The pad is supposed to be completely straight up to the edge, without any "creasing" or other lines at all. Due to the its construction, the foam inside DCA pads tends...

Where is the science in EQ of headphones?
Seems like everyone has a home brew for eq( enhancing ) headphones SQ on this forum. As a science based forum , the directive to just listen to changes does not get me very far. Once someone creates EQ adjustment list isn’t there an objective way to measure the suggested SQ improvements? The...
