Excellent App

I am somewhat of an audiophile on a budget and have a variety of earbuds ranging from cheap Skullcandys for work to more expensive AKGs. The app itself is simply amazing and very easy to use. There is definitely a noticeable difference in sound quality when I tweak the settings to match the frequencies my headphones can reach. My truck also has two pairs of Infinity Kappa 6x8s with Kappa 10 inch dual sealed subwoofers. This app doesnt only work for headphones. The difference is simply amazing as my head unit is cheap and only had an auxiliary jack with very limited equalization options. I highly recommend the app.
