Question Wiko Cink Peax 2

Hello!

I have got a Samsung Galaxy S4 I9505 and in a few days I will have the wiko phone. I have only seen it on pictures in the WWW but the double SIM thing is very important to me and my main use for the phone is listening to music - there and then using google or reading emails.

Can anyone tell me something about the Headphone sound? Is the sound good and - very important, too - LOUD enough?
I read there is a code "*#*#3646633#*#*" and you can go to audio, to another menu and change the value to 160.

It would be very very nice if someone could tell me something about the headphone sound.

Thanks a lot,

lienot
