Earbuds got wet...

about a week and a half ago i got an iPod Mini (refurbished) from Apple. i accidentally left the earbuds in my pants pocket and they went through the wash. i haven't tested them yet, but i was wondering what i should do if they don't work. they were the best earbuds i ever had (they accually stayed in my ears and sounded amazing)...i really really don't want to buy some other brand's earbuds. is this covered under the warranty? thanks..
