I just bought ARTPOP and listening to it, and I'm having trouble finding this holographic sound, but indeed CD sounds better than Spotify even with Fidelify. Day and night difference
I used to have that issue... All headphones sound like normal earbuds to me at the very very beginning of my journey... however, after a full album run down with a different headphone other than my iBuds, then I realized what I missed all the time! That's what brought me here xD
I think the environment you're in also matters a lot...especially if you have open headphones.
When my buddy demo'd my HE-500s he had the fan on at bull blast next to him so obviously it didn't sound like a $700 headphone.
I then tried listening with the fan next to me and it was absolutely horrible.
lol, his profile says he's in highschool. There is a guy I know that is now in college but still looks like a middle schooler : )
(Don't worry, its root beer)
