I think depends on our experience with headphones. Different people heard different headphones, so will have different impressions.

Personally my own impression also change over time. Used to think my HD600 doesn't sound that much better than my HD518 and HD58X. But after listen to a long time and listen back to the other headphones, then can appreciate the differences better. Before this also never liked bassy headphones, but now I'm appreciating headphones with good bass response. Turns out in the past I might have just heard terrible bass.
