Okay more bass and less treble, yes. But it's also doing something weird to the presentation. It feels more closed with less separation and imaging. Even though the overall sound is more closed, the treble feels like it's coming from far away... recessed I guess would be the word.
Anyways, I think at this point I'm pretty decided that these aren't going to do it for me on the HE-4. While they sound fantastic with EDM, they're not to my liking for most other stuff. I'll be trying them on the HP100 at work and maybe breaking them in a little. I'll try again in a few days to see if anything changed. I want to like them... they're really comfortable!
