A:AnswerYes, they have different size ear cushions for different ear sizes. Usually THREE different sizes. Just monitor the volume setting. The child should not start losing his/her hearing until after 50, not pre-teen.
A:AnswerThe guide book in the packaging said it was water resistant but not waterproof. Essentially sweat and rain resistant, but not waterproof for anything too extreme.
A:AnswerThe earbuds are definitely OSHA approved. The earbuds can be used together as intended or you can use just one earbud by itself and it will work.
A:AnswerI use safety googles at work while wearing the earbuds and they fit great. I have also used them while wearing my reading glasses and I hardly notice that the earbuds are there. No problem whatsoever.
A:AnswerWhen I bought mine I read through the little guide book that came with it. It said a lot of problems with the buds could maybe be fixed by resetting the ear buds. Also another common issue I had with a different set of ear buds like these was the metal connects can get dirty and block contact with the charging pieces.
