Elikliv Active Shutter 3D Glasses 4 Pack, Rechargeable Bluetooth 3D Glasses Compatible with Epson 3D Projector, TDG-BT500A TDG-BT400A TY-ER3D5MA

We have a home theater which has a 20-foot "throw" and a 110" (16:9) screen.We recently purchased a new Epson Home Cinema 5050UBe 4K PRO-UHD 3LCD Projector which also features 3D playback in addition to 4K playback (you should see 2001: A SPACE ODYSSEY [1968] IN 4k).As my wife and I have always enjoyed watching 3D movies (over the years we have attended several 3D theatrical showings), we needed to buy some 3D glasses as the projector did not come with any.We have tried several types available here on Amazon. The first pair we got < Elikliv 3D Glasses Bluetooth 3D Rechargeable Active Shutter Glasses 3D Eyewear Clip on Glasses Compatible with Epson Sony LCD Projector/Sony Panasonic > were really uncomfortable though they worked well.The next ones < XPAND X105-RF-X1 Rechargeable 3D RF/Bluetooth Glasses,Black > were comfortable but they were a real "pain" to use as, due to the poor design of the on/off switch, they were difficult to turn on and off and, even worse, they would lose the 3D signal from time to time (often when switching from the 3D main feature to 3D extras).The next ones we bought < [Sintron] 2X 3D RF Glasses for Sony Panasonic Samsung 3D TV, Compatible with TDG-BT500A TDG-BT400A SSG-5100GB TY-ER3D4MU (2 Pairs) > SHOULD have been the best: they are fairly comfortable (at least for me), they function well in all regards, and they are the only ones that I can find here on Amazon that use disposable batteries. Why would we want that? Well, rechargeable devices have internal batteries which will eventually expire and there is generally no way to replace those batteries. Glasses that use replaceable disposable batteries will work well into the future.Unfortunately, though they are quite comfortable for me, my wife has a problem with them. She says they are unwearable for her as they badly hurt the bridge of her nose. After we watched a movie using them, I could easily see the deep mark these glasses left on her nose. (Though they are uncomfortable for her, they are fine with me and I just ordered a second set. I do not know for how long into the future active shutter 3D glasses will be made and I think that it's better to have some extras, ones which will last well into the future.)Except for the fact that these < Elikliv Active Shutter 3D Glasses Compatible with Sony Panasonic Samsung 3D TVs, Rechargeable Bluetooth 3D Glasses Compatible with Epson 3D Projector, TDG-BT500A TDG-BT400A TY-ER3D5MA (Pack 4) > under review here are of the rechargeable type (as noted I prefer those with disposable batteries), they are near perfect.They are VERY comfortable - by far the most comfortable pair we own - and the price is very reasonable (about $32.50 per pair).Even that would be no good if they didn't function physically well. But they DO! They work as well as any of the other pairs we own (and much better than that second pair). The on/off switch is very well designed and these glasses do not turn off themselves if a 3D image is being displayed (even on when it's on "pause" or when switching to extras).We find the image to be somewhat brighter than that obtained with any of our others. Now there is a trade-off for that brightness: sometimes (not often) you will see cross-talk ("ghosting") in the 3D image which, with other, dimmer, glasses you will not see. [PLEASE SEE UPDATE BELOW]Last night we watched the movie THE WALK (2015) which is frightening enough in 2D ("flat") but positively nerve-shattering in 3D. (Take my word for it: it's much "worse" than any horror film I have ever seen, especially if you have problems with heights.)I could see a bit of "ghosting" in a few of the subtitles and a bit more elsewhere, especially in dark scenes. Now please understand that this "ghosting" was very minor and you'd have to be "picky" (as I am) to even notice it. But it was definitely there. Some day (not too soon; my nerves can't stand it) I'll watch this film again with a pair of my other glasses to see if the "ghosting" is still present.I'll also be curious to watch DIAL M FOR MURDER (1954) in 3D using these glasses. This disc is noted for some bad "ghosting" (and it sure was apparent when we watched the movie using one of our earlier pairs). I would guess (though I do not know at present) that the "ghosting" will be somewhat worse with these glasses. Only time will tell ...All in all, however, I'd much rather have a brighter picture than a darker one. 3D glasses at best allow transmission of about 37% of the available light from the screen. That's about what they all CLAIM. But I believe that this one delivers.However, you yourself must make the decision as to which is more important to you: a somewhat darker picture with minimal or no 'ghosting' or a somewhat brighter picture with some more apparent 'ghosting.' (Admittedly 'ghosting' can be annoying.)Your choice.Please let me reiterate: we are using these glasses in conjunction with a video projector and a screen, not a 3D television. I cannot comment on how they would work with a 3D TV (and, in any case, to the best of my knowledge, no one is manufacturing 3D televisions any more).As my title stated, overall these < Elikliv Active Shutter 3D Glasses Compatible with Sony Panasonic Samsung 3D TVs, Rechargeable Bluetooth 3D Glasses Compatible with Epson 3D Projector, TDG-BT500A TDG-BT400A TY-ER3D5MA (Pack 4) > are the best 3D glasses we own (and among the most reasonable priced) and I can VERY HIGHLY RECOMMEND them to you.Thank you for reading this and for considering my opinions.Lawrence H. BulkUpdate December 17. 2020:By carefully re-reading the instruction manual of my Epson Home Cinema Video Projector Model 5050UB I found a small "tweak" in the settings which allows for almost complete elimination of the crosstalk ("ghosting") problem. The other night, after adjusting the projector, we watched DIAL M FOR MURDER which is one of the more notorious 3D discs known for crosstalk. That crosstalk was almost completely eliminated. Therefore these glasses are even better for us than they were when I first reviewed them. They are currently unavailable. I do hope that the manufacturer will create another run of them and that Amazon will sell them again.

3D has taken a lot of twist and turns in the consumer electronics industry. for a while hd 3d was hot. then it all but disppeared. then people like Elikliv realize the hole that is made and develop a product that works well. Documentation even from Epson is scant. But just as Elikliv says in the small printed instructions hold the button until it binds. when they did, a message was visible on my Epson 3700 home cinema HDTV 1080p projector. Tested Wizard of oz 3d, which is amazingly good. Desolation of Smaug. Jurassic Park, and Inside Out. The glasses have a very common USB charging port, they come with small USB charging cables. and the glasses fit over my prescription glasses which was a necessity or these were going back in the box.the push in the consumer electronics industry has been so focused on 4k, that many have forgotten 3D exists. if you type native 4k resolution 3D display in your search, you will be able to sort thru the noise very quickly. but in HD, 3D shines very well. if you have a 3D TV or projector, you should really get a good pair of glasses. these aren't the cheapest but i don't begrudge a penny spent.Good luck to everyone out there.

Comparing them to Panasonic TY-3RD4MU which I found so far most comfortable (tried also Samsung/Epson), they are slightly bulkier and little bit heavier. But still comfortable. Otherwise similar brightness level and picture quality. These have a more bluish/greenish tint or you could say more reddish tint for Panasonic (bluish tint might give illusion it's sharper but they are about the same in that aspect).

Far superior to the Sony glasses that came with my HDTV, in every conceivable way, and at half the price!The Sony glasses are fragile, go through batteries fairly quickly (I'm always afraid the battery holder is going to break when changing button cells) every single one has had one or both legs break off!In contrast, these look and feel quite sturdy, and they retain charge very well. I'm pretty sure that the problems with syncing to my HDTV are caused by the TV, not the glasses. I often have to perform a hard reboot (pull the power plug for 20 seconds, and restart) and stand directly in front of the set within 10' to reacquire the 3D signal. (The latter is what the glasses' instructions suggest should difficulty with the sync occur) this only needs to be done if I haven't watched a 3D source for several days. Again, I believe it is the TV causing the issue. I purchased four, after using them successfully for about a year I intend to buy more ( my home theater is popular :)

They DON'T work. Four out of four pairs never fully charge--red light stays constant when plugged in--and they will NOT sync with any of my 3D projectors. Blue light never stops flashing--can't lock in. I have many other brands of 3D glasses and they ALL work fine. These are a total rip off.

I tried another more low profile brand but returned them because they would keep desyncing from the TV. So tried these and all work perfectly through the entire movie! Build quality seems good so far. Has nose pad which is comfortable for me. Comes with cloth storage bag, cleaning wipe and charging cord. I recommend!

While the glasses did immediately sync with our projector (one of the 4 glasses arrived dead -- could not be turned on), they just didn't do that great of a job. I will say though, that the performance is highly 3D-content dependent. If your system supports creating 3D out of 2D material, I would not recommended that approach -- doing that actually made most of us feel like we had a headache after 15 minutes of viewing it and the effect wasn't that good. Battery life seemed very good and they charged quickly. They're one-size fits all, and therefore aren't the most comfortable for long viewing times. In the end, these weren't for us and we returned them.
