Query: Don't Lose The Rubber Ear Pieces!

I am not an audiophile, but I thought that these earbuds performed well. Where they fall behind is that the removable rubber ear buds easily fall off. There are three sizes that come with the earbuds, but generally only one set fit well. I called Sony and asked for another set.... $15!!! This is my second and last pair (once again the rubber ear buds have fallen off and are no where to be found). Not worth the price if you ask me.
