So I've had these guys for almost a week now. I hated them at first, I felt that the mids and highs were blanketed by something all i heard was bass. Step in Viper4Android. HOLY #*&^ what a difference it made. I have a galaxy note 4 for reference. After rooting my phone and installing this app I only turned on 2 items. Playback gain control (Max gain 2x, max output -1.9dB) and viper clarity (natural, default) OMG what a world of difference this made.I was contemplating getting rid of these but now.. You would have to rip them out of my cold dead hands. The highs and mids woke up and blend quite well with the bass. I wanted something like the UE TFi10's w/ better mids using V4A it just about made that happen.. Vocals are more natural sounding and a lot closer to the front of the stage, before that it sounded like the bassist and drummer were in the front and the guitars and singers were in the back..
