there are earpods or head phones that work off the lightening USB connection now ... and please consider that the ear phone jack is just for ear phones (earpods) not for anything else.
if you want to play music off your iPhone (I like to do that as well) .. then hook it up to a USB port.
That being said, my 5s is only 6 months old and I am now replacing it for a new one as the lightening port is broken and will not hook up for charging, playing music or connecting to the iMac.
Hopefully you have Apple Care as part of your purchase ... and when you ever go into the Genius Bar on an appointment bring proof of your reservation off the email they send you as in a hard copy or in your iPhone to show them.
Sometimes they lose the appointment and they will turn you away.
