They say if it's too loud, you're too old! But you can't hear them say that, because it was too loud when you were younger. Rocking out might be okay for the grown-ups, but kid ears are still growing! A volume limiter will keep 'em safe. And keep you from having to hear Ke$ha second-hand every time they walk past.
Much like a motorcycle and a credit card, headphones give a kid the sense of freedom. They can listen to anything and you can't know what it is! Naturally, that won't be true, but kid logic, you know? Anyway, pre-save them with these sound limiters and they won't even know what happened. They don't even really know who Paul McCartney is yet, so how will they know what volume he's supposed to be at?
