Moto X (2014) :: Why Do Only Hear Audio Through One Earphone

I've recently got the Moto X and out of nowhere, I can only hear audio through one ear when having headphones plugged in. I've used compressed air and blew it in there and I've tested both headphones that I used on the phone on my laptop and they work perfectly. I probably have to send it in for warranty. I can't find the repair request form for Canada and when I do the request online it says "The IMEI is from a different country so you can't get it fixed in the United States." or something along those lines.
