The wireless DMS active 3D glasses are designed to view 3D content on LG 3D TVs. DMS offers a high quality alternative to higher priced active shutter glasses, allowing your family and friends to share and enjoy the full 3D viewing experience. Extended IR receiving window is constructed with a high filter capacity to reduce environmental interference to improve all-around receiving without a "black hole" effect. Unique design of power saving circuit layout and low power saving chips enable the glasses to be lightweight and flexible. Glasses may run up to 24 hours of continuous use per charge. Intelligent auto ON/OFF function extends battery life by "awakening" automatically when receiving an IR signal and going into power saving mode 5 minutes after IR signal is cut off. Confirmed to work with LG 3D televisions.
