I've just replaced these with a new pair exactly the same since the power button rubber fell off these work and connect fine check the list below why I list as for parts power button rubber fell off which i tried to glue but unsuccessful. you can use a pen to press the power button inside to turn on etc charging port rubber blanking has also cone off at some point inline volume buttons show signs of wear Full set of new ear silicone pieces though in small medium and large (I swapped over my used obes to my new earbuds and put the new medium ones on these) what you see is what you get have disconnected all old devices in the Bose app
