I have the LCD-2C but I want the option to make them closed back, could I just buy the cups and swap them whenever I needed?

Nope. Not that simple.

There's acoustic dampening and other trickery in the cups that differ in open-back and closed-back models. Even if you somehow added closed-back cups to the LCD-2C, they would sound like shit because they're tuned to be an open-back.

I don’t see Audeze selling replacement parts for it, nor do I even know what the part is called to search for third party options

The reason is, that it has a function rather than just being cosmetic. I have the LCD2 Closed Back and have opened them up I know there is a wire attached to it and a bunch of foam there hence.

Yeah basically this.

Also it's not very common for people to swap wood cups on LCD-2C.

However it's very common for people to swap wood cups on Fostex/Denon headphones. But those are different size and will not fit LCD-2C unfortunately.

So the best chance is hoping someone sell their LCD-2 Closed as parts.

Any idea what that wire goes to? Someone on eBay awhile back was selling the baffle cups/cups and all I saw was tuning foam.

According to this image, a resistor, inductor, and something we can't quite see. So it seems they use passive filtering in the cup to tune the sound.

Thanks for that link. I have the LCDXC and it's basically an LCDX with cups on it. I wondered if I could just slap the cups on my LCD2C and be done. I haven't heard the LCD2 closed but if they implemented that kind of filter, they must be better tuned than the LCDXC, which is a total mess compared to LCDX (no bass, harsh/painful tremble, unusable for me).

The sound would change tremendously, which is why this is not done.
