Earphones not working

[monkeysrock0622]

I have apple earphones that were made for the iPhone and the right ear piece just stopped working completely and I never did anythng to it. It worked fine yesterday but today just the left one works. I tried unplugging them and replugging them and it didnt work. This same problem happened to me before with the original pair that came with the iPhone so I just bought another pair with my $100 rebate. But the first pair lasted for about 2 1/2 months, and these ones only lasted about 1 1/2. They should replace them for free right? Because I have a warranty for one year on them. Or is it posible that its my phone and not the earphones? I kinda hope its my phone because then they would trade it for a new one (i hope)and I might get an 8gb instead of the 4gb that I have now. Has anyone else had this problem with teir earphones?
