So, I burned in the HE500 again (although it was burned-in many times before). Everything sounds much better today. With lots of impact. I swear the HD6XX throws off other headphone impression somehow. This is what I call burn-in (will keep burning them in, forever...). Appreciating the crisp and sharpness, which sounds a bit sharpened in response. Sharp forwardness, but very crispy sounding like Focals. More modern music that are more processed sounds really great with these, like the music changes to another level that breaks your preconception of modern music. Some people say certain music are badly mastered until you listen to them on the HE500 I'd say.

<- this emoticon is wearing HE500.
I noticed sounds like cymbals have good definition to it. Like there is dimentionality to the sound due to the definition I think.
I'm using the velpads.
I think I went from mainly rock and audiophile tracks with HD6XX to everything on the HE500 (R&B, hip-hop, newwave, whatever have you). Interesting how the headphone directs your music listening. You keep leading to whatever sounds good to you with the particular headphone.
