Theoretically, any headphone can be brought to a mostly flat response using EQ.
Also, I don't use music test tracks, I use SineGen and/or pink noise to see exactly what needs to be done. Test tracks are for confirmation after you've found the correct response.
I sent a message to a mod about getting this stickied. Be sure to voice your support.
well I've found the spikes in SineGen but they don't "fix" my test tracks...and in the treble sine.wav goes very high pitched and resonating....I'm not sure how to know what is normal and what is not.
like learning colors to someone blind, or sumthing
well, we'll bounce this topic until everyone sees it
