SONY TDG-BR250/DBL

This glasses are pretty comfortable I have worn them for a good 3-4 movies and they don't feel to heavy or uncomfortable. I'm about to order more as I need a couple more glasses. Big improvement over the first gen 3D Sony glasses

Sorry, but there is no way I can watch a movie for 2 hours. They are extremely uncomfortable. I would rather watch 2-d.

Excellente active 3D glasses.they charge in minutes.comfertable with clear viewing, gives a very good 3D effect of 3D world created by sony.price is still at a higher end but a great experience of 3D makes you feel worth its price.

I'm using these glasses with 40EX720 and 3D effects from TV - 3D content and simulated 3D - are average. Not much fun watching 3D movies with these heavy glasses. One shall first convince self by watching 3D contents for long duration before buying...
