I purchased a Sony Xperia Z3 few weeks ago and noticed a strange thing. My headphones Beats Solo HD play at less than full capacity. On my last phone, the iPhone 5С and 4S, they played much louder. Very often there is a notice that loud sound can harm hearing. After the volume increases above 60-70% no result can not be heard. How to remove the restriction? I love listening to music loud, and I do not need it. I do not want root access to change only one volume. Everything else works fine.
You could try different music apps, perhaps google music or poweramp
You can also contact Sony directly regarding this request/issue
Any applications will not help, most likely problem is deep in the phone.
Sounds like no pun intended like you were warned about the damage to ears with high volume and you accepted it so the only thin I can think of is a App preferences reset - Settings tap the 3 dots then Reset app preferences which will reset all apps then you need to reboot and test
