Hello I have a Koss PortaPro headphones and i like them very much, the only thing that is bag is the people around me listen some sound through the koss phones (open phones).
I hear mainly hard rock and rock music.

In the same line but with more comfort audition and "better quality" listen through the iPod/fiio x5, is there a better headphones? preferer with a more close sound.
Even with a headphone amplifier considering buying.

some one told me about ATH-50 and the grado 80i.
 
any suggestion??
 
Note:
Sorry for my bad english.

Budget?
 
If you don't buy in the U.S.--where do you plan to buy?
 
You need a closed can.  The Grado is open and leaks as much or more as your Porta-Pro.
