As 3D glasses we have 2x the Sony TDG-BR250 model. I just took the cheapest Sony. One was free when this TV (that was an action of Amazon), the other, we have reordered after several tests with 3D trailers on the Sony Entertainment Network App. First 3D test before still so worried glasses. Tested and approved. ;-) In LOVEFiLM we sometimes "Despicable Me" ordered as a 3D Blu-Ray to test the 3D experience even with a "real" film, rather than only with 3D trailers. That was really convincing, I liked it very well. The dark glasses only very slightly, is hardly noticeable, and therefore does not interfere. The Active Shutter I realize only when the spectacles for the first time recognizes the 3D signal, not after that. The comfort is after a few hours is no longer the best, but I take time into account. Press and on the nose bridge. But I have only really noticed when I set down the glasses after the movie. Within 5 minutes, a pair of glasses for 3 hours is charged, which I find really great. Can you recommend without hesitation, especially the new models still cost almost twice as much.
