4 ears? I wonder how that works. I guess maybe in pairs. Top ears - primary, bottom ears - auxiliary. The top ears could be directional with higher gain to better hear specific sounds and pin-point their direction while bottom pair would work as regular mostly omnidirectional ears to hear everything normally. Another, smaller advantage, could be listening to music. She could have earphones in her auxiliary ears yet still listen with primary ears, though only with directional bias. But wait! Those primary ears are cat ears. Cats can hear sounds up to 64kHz while humans only up to 20kHz. How would that affect music listening experience? Stuff above 20kHz doesn’t matter for listening, because we can’t hear it, but she could. Is there much to hear? If so it would make her listening experience on auxiliary ears quite worse. But obviously it wouldn’t matter if the source is something like MP3 which cuts off at 20.5kHz (in case of 320kbps). Although it still could make a difference, even though we can hear the higher frequencies, our ears have lower sensitivity at those frequencies. So maybe she would still get a better experience on cat ears, right? Most electronic audio sources could sound terrible for her. So there’s a pretty good chace she’d end up being an audiophile. She definitely could hear the difference.
But I am also assuming she’s not deaf, which is also possible.

Ok, I might be overthinking this, it looks good.
The 2nd set of ears are supposed to be like a removable headband. They’re primarily there to make the character more cute.
