I'm looking for a headphone within the $250-$400 range to use with an HT Claro Halo for mostly music use, but also a small amount of gaming. I'm looking to upgrade from my Senn HD 280s. I listen to mainly rock (progressive, indie, alternative), instrumental, ambient (see my last.fm for a better idea). I want an immersive listening experience with a decent soundstage, relatively neutral. I apologize if I'm not being descriptive enough, I'm relatively new at audiophilia.
