I've been secretly using them for a quite bit since you sent the box to me. Small, convenient, and with good sound.

Audio Technica ATH-AD2000
I've heard these a couple of times before and I actually like them for certain special qualities they exhibit. I know people who like them and I know people who hate them. The people who hate them say they have a messed up frequency response and they are right.
These are very open and very fast sounding dynamic headphones. Possibly the fastest dynamics I've heard. Very clean sounding. The AD2000 reminds me of Grado RS1s in that it has a similar midrange. However it does not have that mid-bass bump (nor much bass at all). The treble of the AD2000 is MUCH smoother than the RS1.
If you like the Grado RS1 sound, you are better off buying these and EQ'ing up 100Hz.
There are not FR plots. The waterfall plots below only go down to 200Hz.
A peak at 4kHz that looks very similar to the 5kHz peak of the RS1. Did I say they were very fast and open sounding?

With my measurements - it's mostly the driver or more precisely, the diaphragm and surround material and construction that causes ringing. Voice coil and enclosure design also contribute to this effect. Speaker / headphone drivers are not too different from drums if you think about it - except that ideally they shouldn't continue to vibrate after the electrical signal stops.
I've alway thought that having the voice-coil on the driver as in a orthodynamic could allow for some self-damping of vibrations.
Also, your waterfall plots are great, thanks.post #455 of 93211/4/11 at 3:24pmpost #456 of 93211/4/11 at 4:03pmpost #457 of 93211/4/11 at 4:31pmThread Starterpost #458 of 93211/4/11 at 4:41pmQuote:

awesome :D but just had a question so due to the anatomy of the ear higher the frequency the more damage it will typically cause, well it will be the first to get damaged seeing that high frequencies are heard at the start of the cochlea, so would that mean that sibilance is louder? Do producers equalize the sound out at that peak? So that being said would a perfectly balanced headphone still be very sibilant? Cause that always confuses me, like what is the deal with that, I always spikes around there, do they put it there on purpose, and why don't the producers fix it?post #461 of 93211/9/11 at 3:25pmThread Starter

Sibilance in recordings is wholly separate from resonances (ringing) in headphones. This is why driver ringing between 6-10kHz is really bad - such behavior tends to exacerbate any sibilance already in the recording.
As to why producers (sound engineers) don't fix it? It's because they are lazy or don't care.post #462 of 93211/9/11 at 3:34pm
The overhead graphs make it look like the AD2000 driver is faster than the SR009 despite the much faster decay of the 009. Is that your reading as well? Kind of hard to believe.post #463 of 93211/9/11 at 5:35pmThread StarterQuote:
Bravo! I was wondering if anyone was going to pick that up. Other than the big ridge, it does seem that way don't it?post #464 of 93211/9/11 at 5:48pm
Also, (gasp) the LCD-2 is faster than the SR009. What a strange bunch of graphs. I and it seems most everyone else in the world, always thought that driver speed went in the opposite order- the conventional wisdom is that electrodynamics (thanks Arnaud for the fancy new word) are the slowest, orthos are faster and electrosatics are the fastest.
This adds another layer to the misconceptions we have when trying to perceive driver speed. It seems that not only do most people confuse an FR with elevated treble for speed, but also we confuse fast decay with a fast driver.

The decay is only one aspect of "fast". There is also the attack which isn't seen here but rather in the impulse response and square wave
There are also secondary considerations of "fast" that involve how clean the entire spectrum is after the decay. The 009 is the only one of the above that doesn't have a lot of crap. Also subject to interpretation would be what level would be considered audible? The dark blue? The light blue?
I'll pull up the impulse responses of all three.
