Its not about neutrality its about definition and i felt these lacked it. Like i said i have and have had iems thet were heave in the bass but were not muddy and quite detailed. I felt these were not. Like i said, it could have because i could not get a good fit. Had to use the large foam and still was not good or cumfortable. Maybe a pair of customs would sound much better. Who knows, but i have been far more impressed with far more iems by different makers, but it was a better fit.
