I purchased these new in 2020 and used them for a while, but have been storing them since I bought different earphones. I'm selling them because I don't plan to use them. They power on and work without any problems (blue light turns on when powered on: see photo 3). The main unit and USB cable have been disinfected with alcohol. Other parts are unused, except for the case. When not in use, you can attach the two earpieces together with magnets and hang them around your neck. They are in relatively good condition with little wear and tear, but please understand that they are used items before purchasing.
