What 3D glasses work for this TV I just purchased?
Sony - 65" Class (64.5" Diag.) - LED - 2160p - Smart - 3D - 4K Ultra HD TV - Black
Model: XBR65X850C
Sony TDG-BT500 or TDG-BT400 will work. Need to hold the power button down until the button flashes green and orange. Takes about 8 seconds of holding. Once paired to turn off just hold power button for a few seconds. To power back on after they have been paired once just hit the power button twice quickly.
