I got 2 pairs of glasses of this model with my Samsung TV 40 H6400. They are active glasses, the only currently marketed (apparently) that work with this TV. Each telescope is packed flat into 2 small bags. We must take off the protective films on both sides of the glasses, clip the branches and put the flat battery included. On first use, you must press the button for the TV recognize. Then they are automatically activated when the TV detects 3D video. Wearing these glasses is catastrophic as the distance of the nose is fine. It is important not savachir on the sofa at the risk of no longer see anything. And the battery wears at great speed, and an integrated battery mount an adult would be much better for me, but I did not find one.
