Hi,
It seems the whole measurements of ER-4S at Headroom:
http://graphs.headphone.com/graphCom...phID[]=743
are actually of ER-4B:
This error must be fixed.

Did you measure the cans in an ear?

Oh, not me. this one guy in Japan did the job:
http://fuchinove.chillout.jp/canalsokuteikekka.html
I also compared the good ol' (V1) Headroom ER-4S impedance graph to my own ER-4S impedance graph (measured w/ CLIOwin 6.5):
Your previous impedance graph was actually correct, unlike your current one. I think you guys somehow mistakenly mixed the 4S data with 4B's. (at least the impedance data, if not all of them) Please double check if any other ER-4B data are listed as ER-4S'.

Hate to say it but he's right. The impedance curve for the 4s has changed over the past few weeks, even since it was reposted in the V2 system.

I'll take a look into the 4S and 4B measurements tomorrow. Stay tuned and I'll let you know what I find...

Etymotic ER 4S Impedance Measurement
Yeah, the posted ER 4S impedance plot appears to be incorrect. I'll run it through Tyll and we'll probably get that figure corrected soon. I also noticed the Harmonic Distortion plot looks incorrect for ER 4S, however, the other measurements look valid.

And, I believe, the desire to see some commonly available crap cans so as to see the magnitude of difference between junk and good cans.

by crap cans, you mean like normal ~$10-$20 cheapo headphones from [whatever] brand?
