Sounds like you are having fun.
I went through the same sort of process a few years ago.
I decided to go really budget with a set of goldring NS1000 for 50 quid. Amazing noise cancellation considering the cost.
They don't sound particularly good, but are adequate for the office. I now only use these on long train/plane journeys, as iems are better for the office.
I also bought a set of audio technica closed phones for home use.
I completely agree about tool for the job.
Well said. I don't get the rolling stones either, or radiohead for that matter.
Music choice is so personal, its good to discuss, but not worth arguing about, although I have been known to bait radiohead fans from time to time.
Resolve = being able to follow the start and end of each note, rather than having an amorphous bass 'soup'. Its the sort of bass when coupled with depth and punch that costs a lot. DT770's struggled with that track.
