Okay so I saw this:

OMG DO WANT. Yes, those ears are speakers.

and I think it could be

Vertical Vents and a Node Receiver together in one "helmet side" accessory, with some tweaking to avoid directly copying the real thing...

EDIT for comment #1: or talk to the nice ladies who invented these and team up! I mean sk and these just feel really similar, they might get along *dreams away.*

The body would always be "shadow" (black) with the "toasty" "regal" "dusky" parts etc. being the lights in this thing, with a similar intensity to the Eyes of Fury.

So they would be like "Toasty Cat Tunes" ... "Volcanic Cat Tunes" ... and so on.

prismatic would have prismatic body too, in addition to lights, or just black like regular and have the light be pris. IDK what I'd like moar :D.

shadow would just be epic "black light" or no light? ye. However they can get that RGB mapping to work.

"Supurrr Cat Tunes" would be like the rest (black body), except these constantly go through all the colors instead of always glowing just one.

Purr. As in cat. Supurrrr. I'll escort myself out, thanks.

I would wear...so much.

I'd get these IRL if I had more money to throw at things. And believed that headphones lasted more than a few months before the wire fizzes out. Yes, these come in wireless and wired varieties, I think, based on their website. But still, monies.

Release with the next, idk, "official soundtrack" if they ever do that again with enough changes. If I recall correctly, this would be too appropriate, cause they did change the candlestick keep music a while back, and them places are full of spookeh kittehs.
