This is one of the best inventions for the iPhone. They are little accessories that plug into your headphone jack and dock to protect them from water & dust. They also work in the iPad and iPod touch. Check out my video and pictures below. They are just $9.95 for the set plus shipping and can be purchased at icorkz.com. I recommend them and will be putting them the rest of my devices.
