I just looked this app up and read this in a review that made me lol...
"How good is it? I listened for about ten hours the day it was introduced, and also compared the Apple EarPods with the Dirac app directly to the $1,100 Ultrasone Edition 8 on an iPhone 5. The optimized Apple EarPods are better: far smoother overall sound, loads of deep bass with no fake bass boost, but with far smoother midrange and treble than the Ultrasone!"
I haven't heard the Edition 8, but I have heard the Edition 10 and found the sound downright offensive for what it costs, but man this review is harsh. At least they have a free version of the app so I'll give it a whirl tomorrow. If it makes the EarPods sound better than an HD800, I'm quitting this hobby for good.
Edit: *properly amped HD800, that is
Another reason to never take his reviews seriously.
