The spectacle itself is made of a black-transparent plastic and shimmering light purple when light shines on it. That may not be everyone's taste, but in practice it looks so bad.
The spectacle has virtually no color distortion when bending your head, for though the image becomes a little darker. Starting from the usual, straight posture, there is a tendency latitude of about 10 ° to the right and left. Unfortunately the 3D effect looked on my device a bit blurry. Since I only Universal glasses and no original Sony glasses had at this time at home, I have tested the glasses in the local electric Specialists in more detail. With a Sony KDL-46HX925 it worked just as well and in terms of allowable head position even better than the Sony TDG-BR250. The same was true of a well-tested 55 "device.
I bought out Sony TDG-BR250 2. With this the problem of blurring in small screens occurs no more or hardly.
Hence my recommendation: If you have a screen size of over 40 inches and do not want to necessarily rigidly watching TV, has taken this universal glasses a cheap and good choice. However, anyone who has a smaller screen, should fall back on the original glasses.
