Link here. Head-fi isn't allowing me to attach files so i uploaded it to Mega, hope that's ok.

 

Not much different from mine after all...

What's your thoughts on the change from stock to this?

It reduces sibilance in more sibilant tracks indeed. Of course, very sibilant tracks will remain with some sibilance... but not the headphone's fault in this case.

I find that reducing the 16 Khz doesn't really make much of difference in most tracks tbh. The HE-400's problem area is around 10 Khz which is why it's so sibilant.

Yeah, that's why my curve is a little more accentuated arround the 9khz region. But there's still some bad spots up to 11~12khz... so Raven's curve reduces it a little aswell.

 

Try using the sine² peak curve and put the peak point arround 12khz and tell me what you think. Use linear phase.

I'm guessing Electri-Q is a program that will EQ sound for all programs? EQing in iTunes is awesome until you play a song in a different program, ha.

You need a wrapper plugin to use it with the players... don't know if there's any for Itunes. I use George Yohn's wrapper plugin for Foobar.

Don't forget that you're EQing frequencies in between the bars that won't be shown on a limited bar EQ.  If I EQ'd 3db down at 8khz and 6db down at 16kkhz, then I'll most likely be EQing down 4.5db around 12khz by default.

 

Also realize that sibilants aren't the only problem with an accentuated upper treble.  Things like hi-hats and cymbals are unrealistically pronounced as well.

How would I do that? I tried Sinegen instead, slowly raising the frequency while trying to detect any jumps in volume, it certainly increases significantly at around 9Khz, then goes down slowly and the rest seems too high pitched to even matter.

Well if you wanted to set an EQ curve for all your programs, which includes your music player or even browser, check out EqualizerAPO.

It does matter unless you can't hear up that high! Some would argue the biggest problem of the HE-400 lies from 10kHz and above... Idk, but look at this anyway:

I can actually hear that high, it just isn't as pronounced as said 9Khz hump. But I have still EQed down at 16 Khz, why not. That's the HE-500? Isn't it supposed to have a really smooth treble?

You mean, change the curve type and the mode?

 

To change to the sine curve you need first to change the mode to linear... to do that just go M- > Mode -> Linear Phase. Then, to change the curve, click and hold the right button on the peak point. A window will pop up, then you select Sine² -> Peak.

 

I have done some extensive analysis on the HE-400 with sinegen... detected bad spots arround 7.5 Khz, 9.5(I think, don't remember well) and 11khz.

 

The one that bothered me the most was the 7.5 khz region, but it seems 9 and 11khz are equally responsible for sibilance, specially the last one.

That's the HE-400 with velours.  Here's the HE-400 with velours and what I think the little treble rolloff I implement does:

 

 

 

Here's HE-500 with velours.

 

 

 

 

Notice how both treble peaks don't go above their bass and lower mids, but have a nice little balanced peak and extension.

Thanks for the suggestion. What is the purpose of Electri-Q then?
