Many of the Peltor style ear cups are effectively interchangeable but it's not easy to swap them without damaging something. I've found the black plastic slide outers to be almost impossible to remove from the cups. It's actually easier to remove the slide outers from the wire, although the wires have swaged ends so tend to stretch the tight end of the outer. A little heat helps. This is either perfectly clear or a collection of random words.
