I am still up in the air for IEM, and for the time being going to run with the ATH M-50. Hear great things about it, especially the bass. Listen to a ton of trance.
Anyway, is there a difference between the 50 or 50S? Also do these baby's need an amp to sound great from an mp3 player? If so, which amp?
Is the FIIO E5 what I want?
