I got a pair of Panasonic 3active 3d glasses in the mail on Friday and i was able to test them out over the weekend. I have three pairs of 3d glasses, Panny 1st gen, Xpand X103, and the 3active.
I didn't bother to test the Panny's against the 3active as I find them to be the worst engineered 3d glasses I have ever experienced, but i did do a direct comparison between the Xpand X103 and 3active glasses.
The one thing i noticed right away is how much more comfortable the 3active glasses were than the Xpands. They sit very lightly on the bridge of your nose, compared to the Xpands, which can feel heavy after extended viewing. I also noticed that the image seemed brighter through the 3active glasses, and switching back and forth between the Xpands and the 3actives did confirm that the 3active glasses, to my eyes, produced a slightly brighter image than the Xpands. There was no discernible increase/decrease in ghosting and crosstalk in comparing the Xpands and 3actives.
In addition i appreciate the fact that the 3active glasses are rechargeable (3 hour charge for 30 hrs of viewing), whereas the Xpands require batteries. In all I am very happy with my purchase of the 3active 3d glasses and plan on buying another pair in the near future.
