Wow

Wow... I spent about 1.5 hrs fiddling with the EQ and I was able to turn my 5 year old, $30 Sony XB 300 headphones into $150 headphones at least. I would even say that they are comparable to a slightly more neutral Senn Over Ear Momentum. This was achieved by selecting a reference volume to which all other frequencies would compared to. I applied a 5dB boost gradient to the referenced sub 1khz frequencies like this: 5dB at 30hz, 2.5dB at 500hz, and no change at the reference of 1khz. The tricky part was creating the negative gradient of -10dB extending from 1khz to 10khz, with 5khz being at -5dB and 10khz at -10dB. The app made it simple to smooth out peaks and troughs. The precision mode and the option to choose between smooth and straight curves made it so that I could really fine tune. This was what was needed to really bring the headphone to life. I wanted an app that would give me full control over all the frequencies and this is definitely it. It has a smooth UI, it plays my Spotify playlists just fine, and I havent run into any issues. My favorite part of this app is being able to quickly toggle the eq with one touch as well as being able to change to a different eq with just 3 touches. I cant wait to try this on my car.
