Awesome .. Best eq

Works very well with iPhone 4S no cutting when opening other programs or skipping songs .. Playing with volume or anything else. Sounds tight in the car the bass load is awesome on the subs. Tuning the treble is also tight on alpine e series speakers sounds flawless. No distortion on in heavy metal skull candy ear buds this app sounds great! Would be cool if it worked with pandora. 6 stars
