Question regarding headphone and earphone 'imaging'
What are the factors that can affect imaging for headphones and earphones, I have little to no knowledge in this regard.
I guess stereo crosstalk would make a difference, but even then most audio devices don't have audible levels of leak.
It also seems upper frequency boosted earphones seem to make people perceive a wider soundstage. Is this a causal effect or a byproduct of some other mechanism?
