In ear headphones stopped working from one ear?

I've recently purchased a pair of in-ear headphones for my iPhone. About 2 weeks later (now) one side (the right side) has stopped working. Amazingly, that's also where the remote is but it does work, the actual earbud doesn't though. I'm pretty sure it's not a problem with the jack, since this happens with my TV when I plug them in, too. I'm also wondering if I can get it replaced by Apple and what I would need to take to them to get it replaced if so. Thanks, help is appreciated. (:
