Right ear repair. How do I take it apart?

I’m trying to fix a loose connection on these. Looked at a few tutorials online, but they dont seem to be the same as this one. When I went to dissamble the right ear some tutorials mention a screw behind a sticker in the middle. I removed the sticker, but no screw!.

Anyone know how to get these apart? I pushed the rubber parts through, but it’s still very much connected and I’m trying not to break it…
