In reply to The Lemming:
I imagine that with the same frequency channels, all set to the same levels, on the same phone or tablet, all equalizers will give the same sonic output.
Or are you asking whether all presets (Rock, Pop, Concert Hall, Metal, Classical) are the same? In which case - doubtful, though no one is strictly "better" than another.
This strikes me as a bit of a non-question, but perhaps I have misunderstood.
Anyway I am sure that you will do your usual thing of totally ignoring my answer even though it is posted with good intention.
