Instead, face the earcup up, with the inside facing towards the ceiling. Reach forward and grab the edge farthest from you (across the center from the edge closest to you)- pull towards you. This basically means you're pulling the old earcup away from the edge, instead of pulling it in an awkward direction towards and up from you as shown in the video. It's actually really easy and requires very little force, and will result in very little if any damage to the old earcups.
