I can do a additionnal suggestion. I have downloaded by mistake an app which name is bass booster. And surprisingly, with my music app configuration, this gives a beautifull cocktail !
I don't use bass booster with all kind of music (don't use it for classic) but for pop and rock, the result is very interristing.
Obviously more bass, but also more clarity in voices.
If you want to try, i would be interrested to know what you think about this configuration.
PS : i use the cut bass mode on my fives
