iPhone 6 - Volume limit (music)

Hi all,

sorry for my bad english. 😝

I've compared music volume of my iPhone 6 with an iPod touch (old generation) and the max volume of iPhone is less loud than iPod touch.

In the settings I haven't any limitations, Volume limit is "OFF" and the volume of EU is "NO" (I live in Italy).

Is there a wayto increase the max volume ?

I know that there are many apps like RADSON, Equalizer+ that increase preamp volume but unfortunately they don't update playlists.

i'd like to have more volume with app "Music" of IOS8, so I can update every playlists without any problems.

Many thanks
