I'll go straight to the point: in your opinion, which one is better to listen to EDM? The HiFiMan HE-400 or the Philips Fidelio X1?
Which one has more bass? Which one has better-quality bass?
Comfort, design, driveability, etc... are not a factor. I want you to focus on musicality, enjoyment and fun. For EDM.
HE-400 will be modded with velour pads / grill mod if need be. Don't know of any mods for the X1.
Amp will be a Schiit Lyr.
