Bone conduction earphones & microphone. They're still working now. As it says "junk," they're on the verge of breaking. As you can see in the photos, part of the exterior is coming off. I think they could still be used if you glue them, but this is the third time with this model, so I'll pass them on to someone who knows about adhesives. I liked the design, and the earphones & microphone function was good, but I can only say that there are structural problems. Everything in the photos is included. Please understand and purchase. P.S. I found the box, so I'll ship them in it.
