Down to these two headphones.  My price range is $100ish.  Closed and isolated is a must.  I want balanced sound for all types of music that i'll play off my ipod. Don't have an amp, maybe in the future. Mostly rock, country, some hip-hop.  Having a hard time deciding between the two and have no way to listen first.  Any advice would be really awesome.
