I generally prefer tube-like and laid back sounding phones, I have the HD600 and TDK BA200 IEMs which fit the bill. I'm also looking to buy a set of portable headphones which would be an upgrade over the TDKs. At first I was aiming for the AudioTechnica ESW9 which fits my preferences, but then again I'm wondering if I should get something that sounds completely different from what I already have.
Although I do listen to mostly jazz, classical, and easy listening stuff, I do like the occasional rock song. What do you guys do?
