The 3D glasses I bought for our Samsung H6490, after we have tested the "normal" 3D glasses in the store. We believe that these glasses a lot more comfortable sitting than the others, because on the nose is not a weight together. The battery and radio, or infrared receiver sits imperceptibly behind the ears. Even when wearing glasses, handling with these glasses is great. USB cable for charging is included and the charge itself takes less than half an hour. I invite the glasses to the TV. This is possible as well as the USB hub, computer, laptop, etc. Who is watching a little on the glasses, so that the thin plastic does not break in this lightweight, will have long pleasure. - Quite clear Best Buy!
