The player is what it is. The difference between different headphones is probably more than the difference caused by impedance. I don't know how you are going to compare the effect of using two headphones with different impedances and not have them be significantly different responses too. The headphones are what is different in the equation, not the amp.
sure, but here the OP was concerned about the reverse situation, different daps having different sounds while supposedly measuring the same.
so we end up talking about how the output impedance can affect some headphones, and why 2DAPs with different impedances might explain why they do sound different on some headphones.
so checking the impedance might explain the OP question, and making sure the specs where showing the entire picture is part of the problem.
it's just one possibility, but it does happen more than we know with IEMs.
if EQ settings in daps were all good, I wouldn't care really, but on non android sonys the last slider to lower the bass is at ... 400z. on the X3 you have 2 sliders, BASS, TREBLES... and some just don't have any EQ at all like the hm901. so considering the output impedance goes beyond driving power with most multi BA IEMs.
