Didnt like it that much, was aiming for that bass with my Monster Inspiration, but it just made it worse, its either low bass or a heavy bass with weird popping sounds damaging it!!
Tried DANON Audio and im satisfied so far when using my headset on IPhone, its not the best, but for sure better than this (more bass without that popping sound damaging my headset).
Tried a software called HearME on IMac for EQ, and its the best for EQ so far, I hope to find a similar APP for IPhone. Try it to know what I mean.
