MITSUBISHI-Compatible 3ACTIVE ® 3D Glasses. For Use with External IR Emitter. Rechargeable.

These were purchased in an attempt to get 3D working on my Mitsubishi. I had purchased this company's 3D emitter, and thought I could get it working with Sony Playstation 3D Glasses. It didn't work, so I kept buying and replacing things and changing how everything is hooked up. I purchased these to see if my glasses were the problem, but it still did not work.I called their support line, and ran through some troubleshooting steps with them. Have to say - they seem like a very small company, but they give a crap and are super nice and helpful. We determined that the emitter was likely the problem, so he sent me a new one. It arrived 2 days later. I plugged it in, and it immediately worked perfectly. Glorious 3D viewing is in my future!These glasses are light weight and relatively comfortable. They feel a bit inexpensive (though they are not inexpensive). The earpiece is hollowed out, but so far hasn't been uncomfortable. The temple looks bulky, but it really isn't noticeable. The case and cloth that come with it are of good quality. They will be great for storage.I was a bit confused at the operation at first - press the button and a green light flashes once. Press it again and nothing - thought that was kinda weird, but turned out to be normal. It just means they are on and ready to go. If you hold down the button, you get 3 flashes on the light and it means they are off.I'm happy with this purchase - I actually prefer these glasses to the Playstation glasses (even if I get them working).

Well, I ordered a total of 8 pairs of these glasses as well as the Dimensional Optics emitter for my Mitsubishi 3D DLP. I cna say that they do produce a very nice 3D image. What I can't say is that for the money, it is as good as the theatre quality. Now, I know some of you are like 'you can't expect consumer products to perform like pro equipment...' etc. In short, bull. There is no magic to producing 3D images and there is certainly no magic to the passive 3D technology theatres use. As a matter of fact, these glasses are 'Active' shutter 3D glasses and even by Dimensional Optics own support people, they are superior to what the theatres use. Thats right, SUPERIOR to the "pro" equipment. So, why 4 stars, right? Well, while it is quite impressive, I have noticed a couple things. First, the 'refresh' of the glasses are supposed to be 120hz. Therefore, my eyes should not detect anything, however, I do notice, especially when moving from one scene to another going to black, that the glasses sort of 'refresh' like an old CRT monitor when the refresh rate was too low. Also, I think due to the refresh issue, it takes some people time to 'adjust' to the glasses. Another thing, when glasses sync with the TV, due to the 'active' nature of the glasses, they tend to darken just a tad, kind of like transition glasses. The side effect being that your nice bright crisp picture is now more a darker crisp picture, kind of like wearing some light sun glasses while watching the movie, annoying to say the least. I suppose I could jack up the brightness on my DLP and probably burn through bulbs faster, but, again, you seem to adjust to it as the movie goes on. Lastly, I did call Dimensional Optics support and left a VM which was promptly returned with a super nice dude who was extremely helpful, even though it didn't seem anything he recommended was helping. In the end, I ended up taking a firmware update on my WD-73840 which seemed to help with the 3D quality issues I mentioned earlier, basically, all but eliminating them. Why include them then? Because I still can't vouch that some of this is due to the glasses and some people may not have the luxury of a firmware update to help them out. In short, 3D glasses like similar items, are going to be a matter of personal preference. I was close to sending them back, but, since experiencing the 3D at home with my kids, I like the effect and the price is certainly on par with a technology that is fighting for acceptance by the home theatre market. Not something we will use every week much less everyday, but, I do see us checking out the super bowl in 3D and I am already investigating online 3D content delivery. All in all, I think after all my personal research this was the right move. The product itself is sturdy, but they also not a toy, so if your kids break them or scratch the lenses or you drop them and they break, don't cry about it. They are well built, but still plastic, take care of them like you would your favorite pair of shades, and you won't have a problem. Technically, the idea of being USB rechargable was attractive...UNTIL I got 8 pair of them and needed to charge them all...wow, never really understood the need for a USB hub until now. Kudos to Dimensional Optics for a solid product at a reasonable price. I hope they will stay with the product line.

I just bought a single pair of these to compare them to my NXG glasses. They are pretty much identical in quality and functionality. It charges via USB and holds a charge for a very long time. You can watch a dozen movies on one charge. If I noticed anything versus the NXG, these seem to be just a tad brighter which helps with depth and quality. The fit is also similar to NXG but the NXG glasses may be a slightly more comfortable if you where glasses. One other small advantage over NXG is that it comes with a carrying case that is of much better quality. Overall both products are great and well worth buying. They are far less expensive than popular brands and just as good in quality as any others I've tried.A side note, these glasses worked perfect with the Mitsubishi 3DA-1 adapter and an NXG emitter right out of the box.If you are new to 3D, here is the set-up I recommend:-Mitsubishi DLP 3D TV (any model in the past 3 years)-Mitsubishi 3DA-1 adapter (not needed for 2011 or later)-NXG emitter (or 3Active from what I read)-NXG or 3Active Glasses-PS3 (Games are incredible, though blu-ray isn't as sharp due to HDMI 1.3)-Sony or Panasonic 3D Blu-Ray player (better for movies with HDMI 1.4)-Optional but recommended is a 3D ready AV receiver such as Yamaha, Onkyo, Pioneer or Denon.This will get you rockin' in 3D for far less than an LCD set-up. Plus the screens are gigantic in comparison and picture quality is every bit as good in 1080p. I got my 65" Mitsubishi for $800!
