Think of detail retrieval like the voice of a well trained singer. The really masterful singers (think Freddy Mercury, Whitney Houston) could hit, with perfect accuracy, like 6 or 7 notes in under a second. Now imagine different voices that can do that at different vocal ranges. One person excels at detail in the upper registers but has a kinda husky lower voice. Another has a chocolatey lower range that gets thin and strained up top. Others are superb everywhere.
Then you add dynamics. Some people like Freddy, Whitney, or Ariana Grande could BELT the upper notes without missing a thing. Or they could thin their voice and make it high but gentle. Others can sing super low but their voice goes quiet. Then there’s Barry White who BOOMED the low notes if we wanted.
Then there are dynamics. How well can a singer swap between gentle and powerful full notes?
Headphone transducers behave a lot like these voices. The more expensive units SUPPOSEDLY have performance across several of these areas. But you can always find gems in any price range that excel at at least one or two areas.
