Why does my ringtone work on my iphone?

I purchase a ringtone on itunes and it says its my ringtone when i go to sounds but when someone calls it it doesn't make a sound and it just vibrates

Reset the phone or contact your service provider

It might be on vibrate! Check cause with an iPhone there are three switches (two in settings one on the side of the phone) check the side of the phone where that extra switch is and make sure that that's switched on! And make sure to go to settings and check the sound an make sure it's all the way up and vibrate and silent aren't on!

I have a normal iPhone 5 and I enjoy music but when I listen to my songs only one earbud will work while the other one is dead. I can go on my computer and they will both work so I was wondering why they both won't work on my phone?
