The headphones are not on his ears….
How the hell do you make headphones for this type of ear position anyway?
Ear buds. Simple as that.
I don’t feel like that would make for a very presentable design.
Then they shouldn’t have used headphones at all.
I mean, we’re dealing with a character who can fly by rotating his tails. Which, by the way, somehow don’t tangle up while doing this, yet we’re going to play semantics about him not wearing headphones on his actual ears? Maybe his ears are sensitive and he can hear them just fine in that position.
Hope I don’t come off as an ass, I’m not really being serious about this. It’s just a weird thing for people to be so picky about. I mean, this is a universe with flying foxes, bunnies and echidna. A bee with a dog nose, a cat that can set herself on fire and a hedgehog with super powers created by a mad scientist.
