Maybe, but even if you just lay them out naked" and listen to them they're not very loud, either. ('Guessing here, based on my experience with the similar ones that I had....)
They don't make them for types that wanna "rock out," to be sure!
They could do with a dedicated mini-amp, but then, turning up the volume is easier and okay ... until you forget to turn it DOWN before you use it on another output source!
