If you take the time to read the CENCENELC white paper about portable audio you will find out that there are 2 limits (calculated with bundled earphones):
85 db which could be overriden (EU toggle in the music menu) and 100 db (than can not be overriden unless you jailbreak).
Had 5 months an European 5s and after 1 month with an USA one i can attest that European is capped. American delivers 1 volt unloaded and european about 0.6
It's easy to find out, ipads are not capped in Europe (cause they don't include bundled earphones and CENCENELEC paper can not be applied). Just compare your iPhone with an iPad: if they don't sound equally loud then your iPhone is capped. Since i have the A1533 model it sounds as loud as my iPad where my old european model was noticiably softer.
You can be 300% sure abour these findings. Spent months gathering data and comparing devices. It is as sad as true.
