I am sure your modded HA-S500 will sound wonderful no doubt but. These cans are fully open using new proprietary 53mm drivers.. The scope of sound we are talking about. The stage. Unless you have vents and have open cups on your mod. I am gonna seriously doubt your modded HA-S500 is gonna have the air, the depth, the stage of these cans. Oh yea the drivers are angled too. Did I mention they use new plush cloth covered pads that feel like pillows on your head?.. A different animal. I would say. I want to see one of you guys get these cans as I know you guys would appreciate them like Danny and Ghost both will tell ya.. I am a big fan of these cans. Nothing has given me more WOW moments than these cans.
These simply separate themselves from everything I own. Lol. No exaggeration.
