Sims computer hardware - plumbob mouse & headphones

Back when TS4 was first released there were some promotional hardware items released also. I think there was a computer mouse and a set of headphones that changed their plumbob color depending on your sim’s mood. Does anyone know if there is a way to still buy either of these items anywhere? I’m interested from a collector standpoint. I’ve checked ebay, amazon, and etsy with no luck.
