Eh, I've seen animes with fake catgirl headbands that twitch for silly reasons. It was during a comedic moment so it really can't hold much weapon. I mean, Jaune and Weiss defied gravity for a few seconds. Would that mean they can float for a few seconds as well?

Until we see it twitch in a serious moment, then it's still not proof that it's cat ears.
