I have a set of Sony studio monitor headphones. I can hear more nuance and parts of the music I simply can't hear in any of my ear buds or noise canceling headphones. They aren't wireless, so I don't really use them that often though.

It doesn't matter the cable, the amp, shitty 128kbps mp3 or vinyl. I can hear much, much better with the drivers in them.

I'd say 90% of anything that matters is the driver. But past a certain midrange point, there just isn't really much or any improvement.
