Question: CAn you charge these glasses with any usb outlet or does it have to be with the tv usb?
Document: Sharp 3d glasses are the ones you need for great 3d effect with a sharp 3d  tv .Great glasses will buy again! easy to use with 2d and 3d button. easy charge.
These glasses are perfect, they have different size nose guards, easy to use, easy to charge, and a charge last for a long time. I am very happy with these glasses.
Really good 3d glasses, they make watching tv more fun with the wife and kids. Especially animated movies. Great product for the price.
It was just awful and hard to watch. I am not sure if it was the tv or the glasses or both. These were the ones for the tv model I have, I checked with Sharp before I bought them.
I read the reviews about this 3D glasses and wasn't sure if it's going to work on my 2012 model Tv. So i brought one and try it out. It was great, good thing i didn't go with the cheaper name brand. Great products..i would recommand this 3D glasses.
I received these glasses promptly and in excellent condition, and they are the correct models for my Sharp LE847U 3d tv. I have tried them out and they do seem to work, however, I will say that the 3d test objects are much more noticeably 3d than any of the movies I have watched so far.
There is also a light on top to show the state of charge. The weight is about the same as the old model, and is not objectionable. The glasses are expensive, but all active 3D glasses for all TV brands are expensive (active glasses contain some sort of shutter mechanism that rapidly turns off and on to create the 3D effect). The product works perfectly, and I have been enjoying 3D movies. I highly recommend the 3D movie Hugo.
I bought these to use with my 70 inch Sharp Quattron 3D TV. They work great. Easy to charge. Easy to turn on and off, as well as to select 2D or 3D mode. The only thing I wish is that the lens had a larger area, so that for those of you who wear glasses the experience would be more comfortable. I also purchased the predecessor to these (the DG20 version) and prefer them because their lens area IS larger than with these.
these glasses are the new and 1/3 the cost replacements for sharp's 3d tv sets  i have the 60 inch set and the 4 color system and 3d are astounding . i would highly recommend bying these glasses due to the 1/3 price and the fact that they directly replace the ones that come with the tv sets
I also have Top Gun and it is not much better than in normal Blue-ray HD. I do not think this is the glasses problem because they are light comfortable and definitely show 3d using the tv test pattern. Perhaps I need to adjust some settings on the tv or blue ray player. If anyone else has a &#34;tip&#34; for me, please feel free to respond.
Answer: any usb outlet works - I charge them from my computer, my tv, and my phone charger usb.
