HOWEVER when you open the arm with the charging port about 75% of the way open it shuts off. Sold for parts/ repair. I'm not sure the size 16 - 15s?. but everything is pictured.
They look to be in good shape but only turn on with the arms folded. They will disconnect and refuse to turn on if you unfold them to put them on your face. Also some corrosion on the little circles that charges it, but doesn't affect charging. They're just unusable because they won't turn on when unfolded.
