I unpacked the glasses inserted batteries, switched on and then switched to Fehrnseher to 3D mode. The glasses put absolutely noiseless going after 2 seconds. Typical of this shutter glasses, the image is then slightly darker, so you should slightly increase the image brightness. Now to why I forgive only 4 stars. It still seems a lot of light through the sides and the comfort could be better. She's glasses from the design similar to the cheap cinema 3D.
