I purchased these a few years ago and used them for a while, but I'm selling them now as I haven't been using them much recently. I've confirmed that they can pair and produce sound, but I don't think the battery condition is good. Please note that only the charging case and the earphone units are included; I've disposed of the other accessories and the outer box. I will ship them in simple packaging.
