Nope, still don't get you. The diaphragm moves just like in most conventional designs. These drivers don't produce electrical plasma to any significant degree, the main difference is how the force is being applied to the membrane. The membrane is very strong and stretched airtight, and is itself charged so that it can move in response to the electrified stators. See below image.  The limited excursion is because the electrostatic force is weak, and increases exponentially...
One is light and cheap, but is weak and breaks down in hot water. At least the ones I've used. Another disinfects itself, but is more expensive and tarnishes over time. The last is tougher and will stay sparkling bright for years on end.   It's all about needs.
The Westone 4 is very frustrating phone in that it has the drivers to extend right to 20khz (though it's still shelved), but it is painfully tip dependent. Failing that, since it does have the treble extension, you can always use that taboo tool for audiophilia: equalization. And when using foam tips, roll the foam past the center stalk.   Some measurements to give you an idea of what a different tip does to...
I don't quite understand this. You mean that early versions of the X Pro (and srm-xh) have a circuit similar to the SRD-X?
Different FR, different distortion characteristics, different driver types even. A 2-way balanced armatures in-ear will be very different from an open circumaural in presentation as well. In headphones, full sized ones anyway, you can build a driver to cover the full spectrum of sound, while this is totally impossible for any single driver in a speaker.
The decrease in harmonic distortion with increasing SPL seemed odd; the distortion comparison between the Headroom measurements and Innerfidelity isn't quite consistent.  For certain headphones (e.g. the LCD-3) the decrease in THD+N with increasing SPL corresponds almost exactly to the increase in volume. We might conclude Tyll's system has a fairly high noise floor from that, but his measurements for Headroom show much lower harmonic products for each headphone and a much...
This is damn useful, for the knowledge and as a point of research. Thanks for the chart.
Bit depth, method (VBR, two-pass, etc.) will matter here. Some iteration of the codec are better than others.
A recently disgraced Nigerian nobleman recently contacted me to advance him an HD600 so he could use it to flee the country. For my trouble I will recieve two pairs of the Orpheus. I'm so excited!!
