Sound only from one earbud.
I have a Iphone 5S white that isnt 1 year yet.
I got it from a friend, and after some testing I found out that i get sound only from the right earbud.
I have changed the entire Minijack\charger port. And i still got no sound in the left earbud.
I also have updated to IOS8 and Restored the entire device.
