Hey there guys yesterday I had a pretty good deal on 6S so I took it. Had the Moto X Pure which I will be selling I am not a fanboy or anything just wanted to give iOS a try again. So far I am ok with everything but sounds quality over bluetooth. I was spoiled by viper4android and wanted to know if there is anything to improve add extra bass etc to some music apps. I use spotify which as equalizer so that's good but few others don't. Thanks for any tips if there are any.
