Loving es10, but could not help myself and modded it.   Basicly i replaced Philips L1 driver with es10s. More Pics are comming!      

Very differnt for everyone, but i would suggest to change the ringtone for a louder one. Its as good LG G2 ( and for me thats very loud )   Standard ringtone and notification tone have no chance in loud environments.

This is with no eq and Stock Software.   Cant comment on iphone and galaxy s4, have not heard those.

In my opinion, its the best I have had on a mobile, through head phone jack. A short list sorted by audio quality with best on top. (subjective of course)(I have owned them all, but not long :) ) Nexus 5 Nexus 4 LG G2 Sony Xperia Z Its a fuller sound, better soundstage i'm quite pleased with it.
