For Audiophiles, adds "color" and soundstage to your music

Has a number of useful preset audio settings for your Ipod touch/IPad/IPhone as well as 3 more user-programable settings and while it isnt exactly an equalizer, has useful settings to drastically improve the soundstage and instrument/vocals separation beyond what your IDevice is capable of. It does also have a reverb and "Bass Boost/Bass Crossover" type of function.
I would highly recommend this to anyone who has considered buying an amp or amp/DAC for their IDevice or even those who run their IDevice through a computer-based equalizer and want something for on-the-go.

Pros:-Amplifies and adjusts Bass and to a lsser extent mids and highs to suit a number of audio devices, docking devices, headphones.
-Adjusts audio soundstage to give you that "Sitting right in the studio", "Front Row at the concert" feel
-Adjusts Vocal separation so that you arent just listening to a wall of sound coming from inside your head, you can virually pick out each vocal and instrument on studio/live recordings
-Still allows you to access all your song controls while in the app.

Cons:-Goes to first track in library every time the app is opened, not the last one you listened to.
-Not an inexpensive app, but sooo much less expensive than new headphones or an amp/DAC.
