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.
