Ok, first assessment: the hd25-1 II is more accurate, and is more of a reference quality hp. It's not 100% accurate, but it's closer than the Incase Sonic. The Incase Sonic is a super FUN sounding hp. It's got booming bass, and the highs are pretty good - but forward. The mids needed a little EQ boost, but are still quite nice. This is a quite warm sounding hp.
As for comfort, they're really nice. It feels like I'm wearing ear muffs,...I like it. I think I'd compare the way they feel to the AIAIAI TMA-1 in a way,...but I like the SQ of these better. The TMA-1 lacked the clarity I require, these are nice and clear. I even like these a bit more than my Aurvana Live's,...and that's saying a lot.
Oh, yeah, speaking of the Aurvana Live,...even after I put foam in the Aurvana's the isolation sux. The Sonic's are MUCH better when it comes to isolation. I think they're on par with the hd25-1 II. I'll see if a day or two of listening confirms this.
So far, I luv 'em. But, I DID swap the cable for one WITHOUT the inline iPod controls. I'm using it with my Sony NWZ-A867, and the inline control is useless. I did try it out with my classic, and it works perfectly. And, my classic sounds EXCELLENT with it too!!!
I figured I needed to add that last bit,...
