Trying to disassemble Logitech g332 headset

Hi, I recently accidentally cut off the cable on my logitech g332 headset (not my brightest moment) and I was planning on opening the left earphone and replacing the current built in cable with a headphone jack (similar to this video https://www.youtube.com/watch?v=FfV3xplj...). However, when I was disassembling the headphones, I got stuck after unscrewing the third screw underneath the earphone pads. It seems that the only way to take it apart is to force it, as there only appears to be three screws, but I was wondering if there was any other course of action I could take. I can update with photos if needed. Thanks!
