I've got a pair of headphones which I want to EQ passively to make them sound neutral. The entire EQ is a single low shelf attenuation filter:
I would like to replicate this with a small circuit I could put between the headphone and amp. However, I cannot find any easy to understand or complete information on how to make this. If I had an explanation of the circuit design, what values to change, and how to calculate them, I could perhaps get somewhere and attempt to build something with some components. But everything I am finding online makes me think I'd need an electrical engineering degree to even begin to understand half of it.
The effect of the EQ is shown here:
The headphone luckily has a simple linear slope down from the mids that is trivial to correct with EQ. It is a bit too warm for my tastes without, but with it could replace my HD600 as my main headphone.
