Hi guys, I'm getting my first pair of open headphones preferably 300USD or less , currently torn between the fidelio X2 and the HiFiMan HE400. I can get a refurbed HE400 for 250 USD or either ones new for 300 . In terms of soundstage which is better? I mainly listen to movie/game OSTs and some electronic or bass heaby music, what would be your recommendation guys? If there are any other over ear open back headphones which rival these I'd he interested to hear about them! Thanks !
