I didn't find this thread mentioned on the nexus 5 xda threads but it does support kit kat now so might as well spread the info. For those who never used viper4android, on the FX version, it is more than just a equalizer. You get to put in some tweaks like audio gain, reverb effect, bass boost, and a few more. Best of all it stays on no matter what (you can turn it off). You can use it on Google play music, dood's music player, pandora, 8tracks, etc.
This requires root and installation is very easy.
(-UI setting- in the viper menu is where you can unlock the hidden audiophile stuff I mentioned)
Here's the xda thread of the app

The files are not flash zips they are just regular zips with 2 apk files compressed, one for gingerbread and the for jellybean+beyond
