iPhone 4S earphones under warrenty have broken (rubber peeled and wire exposed)?

My warrenty expires 26th June 2013. I've had these earphones for 11 months but for 4 months they've seperated from the rubber casing and wire is exposed. This is literally from using them once or twice a day. The rubber casing peeled from the wires on the jack and the mic control region. Consequently, the left ear is broken and there is no sound. Will this be covered for replacement? The damage I mean? I don't want to send them in then be charged if they deem them not acceptable. Thanks.
