I should have seen this merch coming.

I'd be more interested if I could use these as actual headphones 
@polychrome ...these aren't headphones?... aw c'mon what a missed opportunity. like even without the kamen rider stuff, this is such a cool robot-girl/boy/friend aesthetic thing
@polychrome that would be kinda rad? Hacking it so it's a pair of comfy bluetooth headphones and maybe the lights change colour depending on the whims of the user? robot 'ears'
@Nine I know, right? Well this IS a kids toy.. but they know adults still watch this thing. I dunno! I agree it's a missed opportunity.
Should be possible to DIY atleast.
