Updated: OneOdio contacted me, then painlessly and quickly made everything right. Good for them. Upgraded my overall rating accordingly. These headphones feel great and sound great. Weird stuff can happen, but they made good.Previously:I don't know whether something snapped or unglued, but while one side is firmly attached but still rotating, the other side dangles loosely with the piece of plastic coming entirely out of the casing... it feels like it's only now attached by the cord inside the little plastic tube. It no longer fits comfortably on my head, and in spite of being well taken care of, didn't even make it to the one-year mark.In the included photo, that plastic should be slid into the hole snugly and shouldn't come out.
