Sennheiser IE8 vs. Panasonic hje900

my hippo vb's just officially died. No more sound from the left side.

Im looking to buy new headphones to replace em and i have narrowed it down to hje900 or ie8.

I mainly listen to hip hop ; A tribe called quest, kanye west, jay-z, immortal technique etc. but at the same time i listen to a lot of genres. The only thing that annoyed me about the hippo vb was that some rock songs did not sound very good on em.

So given my situation which one sohuld i go for (they are available for nearly the same price in my country so price is not gonna be the problem)
