Volume botton not wrong on iphone 5?

I got my iphone 5 about 3 months ago, I got a update on the iphone maybe a week ago, my phone was working properly till I updated it and maybe a hour after the update I was listen to music, when I tried pressing the down button it didn't want to work, I now have to press it a certain way to work, I haven't dropped it or nothing since I got it. Will AT&T or apple store fix this, I'm not going to pay 100 dollars just to fix something I didn't have to do with. Will AT&T replace my phone or repair? How long will it take, please and thank you- I also got my phone with my uncle In his contract do I have to go to AT&T or apple store with him? I'm 16, and since it wasn't my fault will I have to pay? Also after the update my phone started skipping songs when I tried to play them

Sennheiser better than standard iPhone earpods?

I was just wondering if Sennheiser headphones(419/229s specifically) really did sound better than the apple earpods the iPhone 5 comes with.

Okay so I'm talking crying over them because they're so beautiful or whatnot. Like having pictures of them saved onto your iPod or iPhone or something like that.
