Xpand X104LX1 YOUniversal 3D Glasses, Large-Blue

Like so many, I have done extensive research on glasses, compatibility, battery life and etc. The newer "standard" (look up "M-3DI") for IR glasses hasn't really gotten off the ground despite backing from heavyweights such as Sony, Samsung, Hitachi, Mitsubishi, Toshiba, Viewsonic and XPand. But I digress...I have purchased 8 of these glasses to use with my Epson 6010 and have had them for several months. Two were purchased "used" through Amazon. All of them have worked great. The first time you turn them on you hold down the "on" button for a second, then let them sync. It remembers your TV/projector after that and I have never yet had to reset any of them.I personally cannot see a difference in visual quality between these and the Epson OEM glasses that came with the projector other than a shade darker in dark scenes. The few times I have had a full 10 viewers watching a 3D movie (8x Xpand, 2x Epson), you can be sure not everyone was in the sweet spot. None have ever complained of the 3D losing sync or having to hold/tilt their head "just-so" as other reviewers have experienced. Looking back and forth while wearing these glasses also does not seem to affect the sync.We have a pretty good selection of 3D in our collection. The IMax 3D Under the Sea is just amazing using these glasses. From the "3D Tahiti Tidal Wave" to "How to Train your Dragon" I have not seen any significant ghosting or artifacts. Avengers 3D also looked very, very good, though any movie is hard pressed to match an IMax film for effect.The batteries seem to last at least 5 movies before recharging them. I suspect that only one needs to be charged that often but haven't tracked it. They will charge enough to watch a 2hrs movie in about 15 minutes on a dedicated 2000 mA charger, longer if plugged into a PC.Our glasses have seen a lot of use, primarily from kids and are often covered in fingerprints despite pleadings from parents. They have taken some light abuse and still work great.These glasses also seem to support several 3D protocols including the M-3DI. They worked great on my neighbors newer Sony XBR and have a pretty good list of compatible devices. The best place to do research if you are just getting started is the AVS Forums. The complete compatibility list is on the Xpand website. If you have a newer TV/projector, these will almost certainly do the trick.PROs- Lightweight- Can withstand some abuse- Ease of Use- Good 3D sync, tint, low cross-talk- Fast charging/Long use timeCONs- Still too expensive- Not good for use with prescription glasses- "Large" size still not big enough for everyone

Confirmed unit works with Panasonic Viera TC-P55VT50. HW Looks good and works great. Confirmed to work with Bluetooth sync Viera TC-P55VT50. Would've given the unit a solid 4 to 5 stars if my support experience was better. This company has a documentation and support issue. There were no indications anywhere on the documentation and support knowledge base about the RF dongle working with Bluetooth sync TVs. For proper setup, download and install latest firmware to the glasses using the PC and firmware update tool. Set the protocol to RF. Disconnect the glasses from the computer and turn off. Connect the RF dongle then turn on the unit. Press and hold the power button on the glasses until it starts to blink... about 3 to 5 seconds. Open your TV menu to the Bluetooth devices (Have not tested without going to this screen but I'm merely posting what works). You will see on the bottom right of the TV screen that the glasses connected. Repeat the steps for multiple glasses. Red X symbol on the side of the glasses will blink several times quickly indicating that they are in sync with the TV. When you properly set the glasses in sync mode the X will ramp up and ramp down to indicate that it is in sync mode. Note: it's hard to tell when the unit is off and when unit is on. Pressed once the shutter will turn black then clear (means off), Pressed once (again) unit turns on. I'm going to guess that the glasses in RF mode actually is able to speak Bluetooth protocol because the blinking patterns are very similar to how BT headphones sync. When you get it to work, these glasses are the best looking works well. Don't feel like a geek wearing them. Support and documentation is terrible. If you look at RF dongle manual, it is said that it is only used when trying to sync with Samsung. If you look at the compatibility it lists RF and x104 which is correct but doesn't explicitly say anything about the fact that Panasonic uses Bluetooth. When talking to support, they try to weasel from responsibility because I was using a 3D video streaming box as a source. Sure there is a remote possibility of this but better troubleshooting would be to put TV in 2D-3D mode to eliminate the unknown. Repeated asked how the Bluetooth TV to RF dongle works. Support kept repeating that it just works and you don't have to do anything. Support person clearly was not experienced in troubleshooting. Very dodgy support... should get back to selling used cars. It doesn't take much to write up a few examples. Download the manual and try reading how to set this glasses to sync to a different protocol without the PC, yikes. The medium is a bit smaller than I thought and fit my 5 year old. Blue large was a better fit. I have 2 of each.

I bought these with the hope I would finally get simulview to work on my projector. For those of you who don't know, simulview is a Sony technology supposedly exclusive to their playstation monitor. However after the firmware update I am very pleased to report that these glasses work perfectly for this, but not without some trial and error. First off just getting my computer to recognize the glasses to perform the firmware update was a real pain. I bought the cheap 3DTV Corp IR Emitter off Amazon ($19) I almost thought I needed the $65 one but the cheap one works fine. Once the glasses are updated my computer instantly recognized them. Then it was a matter of setting the lense to function with the emitter. After some trial and error I found the xpand emitter setting to work best since there is no option for Optoma projectors or 3DTV corp emitters. After that it was just a matter of starting a game in simulview on my PS3 and double clicking the on button on the glasses. I have searched high and low for the answers I have outlined here and in the end came to find out how to do all this by basic trial and error so I hope this helps anyone who is interested in doing this on their setup.
