I had the second generation TY-EW3D2 and decided to try the TY-EW3D3 because I didn't like the fit of the D2s and they left a red mark on my nose after watching a film because they were a little too heavy. Initial impressions were that they had forgotten to build in the battery and electronics because they weigh the same or less than a pair of plastic sunglasses, probably less than my Oakleys. They fit much closer to my face and eyes, which improves the field of view and is much more comfortable. The greater field of view means that I can sit in a wider variety of positions and be more comfortable. With the the TY-EW3D2's I couldn't lean my head back on my sofa because they sat too far away from my eyes and the frame obscured the screen. They are so light that I forget I'm wearing them and they don't leave red marks on my nose. Charge time is very quick and they seem to last forever. As other reviewers have commented, if you have a reasonably bright light in your field of view then flickering is evident, perhaps more so than the TY-EW3D2's but your brain adjusts for this somewhat and you probably don't want a bright light source in your field of view anyway. They let more light through than the TW-EW3D2's, which makes the picture a little brighter. 3D films and games are excellent and aside from being slightly brighter they share the excellent performance of the previous model. An excellent improvement Panasonic, thank you. Slight niggle is that they don't come with a storage case like the TW-EW3D2's do and they don't fit the previous model's case. I guess I'll have to find some smart looking sunglasses cases for my living room to keep them free of dust and protected from accidents. Overall - brilliant 3D glasses, you can't go wrong.
