Corrective EQ filter for Fostex T50RP MK3

After spending some time really listening to my MK3's with the HM5 hybrid pads, I decided to see how good I could make these sound before even cracking them open to mess with their guts.

This is based off of the hybrid pads, as that's what was on them when I measured them, and it's what was on them when I did sweep filtering to listen for peaks. The final settings were based off of what I heard primarily. The end results is well extended, very smooth, and very comfortable (removes a TON of sibilant peaks and harsh areas, as well as boomy crap). Basically you won't have to mod your cans to fix those specific problems now.

How do you EQ your headphones? You COULD use Equalizer APO and go system-wide if these are your primary cans. OR you can add an impulse response loader in Foobar2000, where you can simply import the file and it'll be EQ'd. Magic!

I recommend finding the VST loader plugin for Foobar2000 (Google it), and then downloading a free impulse response loader like this sleek looking thing: http://www.plektronfx.com/ircab.php

Then into that, load this .WAV file: https://www.dropbox.com/s/btabquc342y6r9j/MK3 correction.wav?dl=0

That will apply the whole EQ instantly. Make sure the plugin is set with "mix" all the way up, so only the processed signal is in there!'

If you're using Equalizer APO, or you're patient and want to use your own EQ software, use these settings:
