Um, no offence, but, are you sure it's safe to use already used earphones (even gently) I mean I'm sure your ears are clean and the earphones have been sterilized. And the earphones arnt going to kill anyone (I mean, unless they are strangled with the cord... which wouldn't be the earphones fault.) But they are going from inside one persons ear and into anothers. Kind of like sharing mascara or contacts. No offence. It's just a question and I don't see any reason it should be repprted. I am mostly just speaking in general, not to you directly. As I said, yours are probably fine.
Well jamie just to set the record stright the ear buds come with an extra rubber piece that fits on the ear bud and goes into the ear therefore it would be like a new ear bud. It qill be the buyers choice to change them if they wanted to also the ear buds have been sterilized
