I think if you are fine with sacrificing a little bit of quality (less bass response) when listening to bass heavy music (ex: rap/hip hop/dubstep/ some rock), you will enjoy the SE425's. They are a bit more well rounded and sound pretty good with just about any genre of music. It sounds like you listen to a variety of genres.
I don't know how else to describe it, but the RHA's sound a little bit "clubby" or "electronic" - this is not probably how you want to listen to jazz, blues, etc. The RHA's will probably sound a bit better when listening to rap/hip hop/ dubstep, but may be less than optimal for the others that were mentioned above.
The SE425's are most likely your best bet.
