Although the replacement itself is inexpensive, it should be known that you have to have a special tiny screwdriver with a "star-shaped" head to remove the screws and put in the replacement. Although evident if you look closely at the headphones it is worthy of mention, perhaps you can order this piece and the screwdriver you need at the same time and avoid waiting to get the appropriate tool.
