I was especially talking about Hifiman... I would never say that Hifiman's products are for everyone. I wouldn't say this about Audeze either.
I agree..some prefer the sennheiser's or grado's or fostex's or beyer's. Everyone has its own preferences..BUT..imho the he500 comes close to everyones favorite..if that could exist..it maybe isnt the best phone in any area... But also doesnt have big faults also. So its safe bet with every music u throw at them..but u do need the right amp! Imho
