Sony TDG-BT500A / TDG-BT400A Active 3d Glasses for 2013 or Later Sony Tv

I needed 3D glasses for my Sony TV. These are the best, compatible ones available. The glasses I received came without the individual boxes but they were packed two together in a foam sheet, and inside, individually packed in a plastic bag. They appear to be brand new, with the little plastic insert to prevent the battery from being drained. The glasses were free of any signs of wear and tear, and there were no scratches on the lenses. I tested each pair, and they all worked with my TV without any problems. The price from this company was far better than anywhere else. They retail for about $50.00 / pair. This company shipped them out promptly, and they were packaged adequately for protection.As for the 3D glasses, the are an excellent match for my Sony TV. These are "active" 3D glasses, and that is why they require a battery, and they must be turned on and "paired" with the TV before they can be used. "Passive" glasses do not need batteries, and are useable as soon as you put them on. I have no means of comparison, but the 3D effect and clarity are very good. They are quite light weight, and so can be worn without being noticeable when you wear them over your regular glasses. The design is a bit odd, in that the frame that holds the actual glasses is not attached directly to the "temples". The temples attach to an extended "bridge", which is then attached near the nose piece, which carries the actual frame with the glasses. I hope that makes sense, but I don't know how else to explain it. The first picture shows you a top view of the glasses which may make it clearer. This is probably to allow the glasses to "float" in front of your regular eyeglasses. The temples tips are also straight, and don't have the curve to hook around the ear. This is probably to accommodate as many different people, with and with out eyeglasses as possible. The lens are a bit on the small size as compared to other 3D glasses, and if you wear larger regular eyeglasses, they may not cover the entire lens. You will need to look through the center of your regular glasses, to see through the 3D glasses. Overall, they are very comfortable, and you don't notice them while watching an entire 2 - 3 hour movie. You really need more than the 2 pairs that come with the TV, if you want to share the 3D experience with more than one other person. I would suggest you buy extra pairs now, because as technology changes, you may not be able to get compatible glasses in the future. One word of caution, I had a few of my nephew's and nieces over to watch a 3D movie, and as soon as the movie was over, they all took of their glasses and threw them on the chairs and left! I guess from experience in 3D movie theaters!? There was no point telling them how much each one costs! I make it a point to collect all the glasses at the end of the movie, turn the battery off, and then use a microfiber cloth to wipe off all the finger prints and pop-corn butter off the glasses before I put them away.Note: These glasses don't come with a case, so I would suggest you buy a hard shell case to store them in. Because of their odd shape, they require a case that is much larger than for regular glasses. By trial and error, I managed to find these reasonable priced cases here on Amazon:http://www.amazon.com/gp/product/B0053CW8C8?psc=1&redirect=true&ref_=oh_aui_detailpage_o02_s00They are a bit of a tight fit, but the glasses do fit, but only one way. The glasses have to face you, and you may have to fiddle with it a bit the first time, but they do protect the glasses well. The attached picture shows how they fit.

Just bought a new Sony 3D tv to replace our older model. The set only came with 2 pairs of glasses and we often have family over (plus there are 4 of us). Expensive but just like the ones with the set and work great. Pairing is very simple. Expensive but worth the cost.

The glasses work well for Active 3D viewing. These are actually hard to find - partly because, while 3D is cool in the theaters, it turned out to be just a fad in the home. People ultimately want 4K viewing and HDR (new upcoming format). They want a stunning picture, not a novelty that actually reduces resolution (slightly). These glasses chew up batteries, but they have some features to help mitigate this issue. They have a small light, easy to see but not distracting while viewing, to determine if they are on. Also, they turn off it they don't sync with a 3D signal after a minute or so. If you have the equipment to support 3D, get the glasses. The worst thing is having the Sponge Bob Movie in 3D, 3 people, and two pairs of glasses (sounds like a real example - it was...).

Only one pair of glasses out of two I bought worked and they where a little annoying. They look great but depending on if twoWork at once accurately willSay it all. So far really disappointed in these pieces ofCrap.

These 3D glasses work well with a compatible TV. They are comfortable enough to wear even over my glasses.The nicest thing for me is that they are less than half the price of those I had to buy for my first Sony 3D TV.My rating is lower based on three things:1) the glasses come with a rubber/plastic nose bridge that is removable. Removable means they also fall off. The nose bridge part is clear and is difficult to find on any background. I purchased 8 of them. We have lost one already and spent several man hours looking for 5 others that have fallen off (only 3 have actually fallen off, but it seems like once they do, they repeat easily). All this in less than a month of use (probably no more than 30 use by as many as 10 different people). It would help if Sony had made them in a neon pink or just about anything other than clear. At least then they would be easier to find.2) #1 above would not be an issue if Sony sold the nose bridges separately. Try as I might, I cannot find them. I'll be honest, when I lost the first one I was hoping to easily find a package of 2 or 5 or 10 to buy just to have on hand. Nope. Sony doesn't sell them. The only place I found them was in England and they cost more than the glasses.3) Sony's web site is difficult to navigate and frustrating if you want help. Support always led me in a circle to FAQ. I didn't need FAQ's, I needed info on how to buy replacement nose bridges. Sony doesn't even have an email you can write to about this. The links they show all lead to additional links. After too much searching I found a number to call for parts. I was on the line over 8 minutes before I could reach someone. That person transferred me and I spent another 25" (mostly on hold) to find out that Sony would sell me the part for $28 (the glasses with the nose pad are only $48). I spent another 30" on the phone trying to get them to back their product. Eventually I was transferred to Technical Support who told me the products were out of warranty (30 days with the purchase of a $2200 TV) by 12 days so I would have to purchase them. So I was transferred back to customer service. Where I sat on hold for another 54" before hanging up, still without the parts I need.

Excellent glasses. So light you forget you're wearing them. Paired up perfectly with my XBR-75X940D Sony TV. No need paying extra for rechargeable glasses. The batteries used (only one needed per set of glasses) last approximately 100 hours and are dirt cheap to replace. They're also simple to manage and the one time registration required couldn't be easier.
