Started with Senn CX 300s...

Onto Monster Turbine Pro Copper...

Then got the Senn Amperiors last week for on the go use.

And then obviously the modded Senn HD555s for home use.
I mostly listen to instrumental goodies and some more classic stuff (think Eagles, Fleetwood Mac, etc).
I prefer the HD555s for their neutral sound, not too dynamic. With the mod they lost some bass but allowed the mids to come out a bit more.
The Amperiors are great for on the go use and very dynamic. However they are quite sibilant at times to my sensitive ears (and push kinda hard on the head).
Turbines are mostly neutral with a punchy but not very defined bass. Good for most pop music.
CX300s... I try not to use them if I don't have to lol.
