Using the plastic opening tools, gently pry the speaker from the headphone's base.

There will be some tearing involved, but this is necessary to remove the original cushion.

The cushion is bonded to the headphones with a circular adhesive strip. If you plan on reusing the cushion, try to keep the adhesive attached to the cushion during removal. This way the cushion can be easily re-attached to the headphones after repair.
