Its pretty neat, but needs more headphone presets

I have a nice pair of Denon AH D5000 headphones for home and Bose MIE2i ear buds, and although there are no presets for these, I could see this app replacing the music app for me. I do like the ability to widen the stereo sound from my earbuds, and the equalizer works far better than Apples (because it doesnt distort the music at all)
