Question Moto G Music quality in earphone

My Moto G "Dual sim" audio quality is not up to the mark as express by Gsmarina.com lot of there is noticeable distortion in music output with earphone (Senheiser CX180), even my LG GM200 output is Far better in term of quality (not loudness). Moto G is really loud but quality is poor, I did install some music player (player pro, poweramp, neutron etc) to tweak with equalizer but with those sounds goes more creepy, but in "play music" audio is OK not Great, if Motorola would allowed to customized equalizer it might be better but its not even with Custom profile. can any one help me for better audio output. Thanks in Advance
