Yes works equally well as Equalizer APO Tried MathAudio as a test of EQ in general its very easy to work with I recommend it, not used fb2k in 15 years and never an EQ program was rolling in 10 minutes. Btw I'm using EAPO because i want the headphone EQ for all audio on my PC .
If foobar was my only source i would be happy with MathAudio.

Anyone else that has measured this headphone and conjured up some reasonable attempt to EQ it
Reasonable= some semblance of technical skill and organized scientific approach , so that the result could somewhat apply to others.
