Fujisawa what is your source? Cause if the source impedance is high they become bright. IMHO source should be <1 Ohm to sound their best.
BTW big thanks to Dsnuts for starting this thread, to mugen3 for the nice reviews and to PeterDLai for made me pull the trigger with his price attacks.
iPhone 5, which has impedance of 3.27 - 4.5 Ohms depending on what you read.
