Might be..but I don't think so..all lumia wp8 should be same.. recheck..(I meant if u have just bought 520 n yet to explore it)..open nokia music..now if u go to settings directly u won't find any equalize option ..go to "my music" where u can see all ur local audio files.. Tap to play..now on current playing track page u will get "audio settings" under option situated at bottom right corner..n u will get equalizer n dolby enhancements settings.. Make sure u are listening through ur headphones.. Else those settings are inaccessible.. Let me know
