Where to get good kids headphones??? I bought my son a pair of cartoon ones at dollar general and they got volume limiter built in and when I plug it into my sons tablet I can barely hear a thing. I returned them and got another pair and also can't hear out of them. I think it's my sons fire tablet is just low and not picking up good through the headphones
