Now we have a way to allow all our students to use the same earphones, and they don't mind changing the little ear cushions. It is easy to take them off and put the new ones on, so I don't have to worry about it. Our computer lab really needed some headphone covers as well, so we'll give those a try as well. Your delivery is fast, so when we need more, we will be back. (Posted on 3/20/12)
