3D Glasses: The Sony TDG-PJ1 active 3D Glasses give you the option to enjoy 3D (three-dimensional) pictures and graphics on your compatible Sony ES 3D-ready front projector. You can enjoy an immersive, realistic movie and gaming experience in Full HD 1080p from your Sony ES 3D-ready projector using the Sony 3D Active Glasses and an HDMI connected 3D source; such as a Satellite Receiver, Blu-ray Disc Player, or PlayStation gaming console (all sold separately).

Optimized For Front Projection: The A matte black interior frame is used to reduce reflections and an integrated polarizing filter make the glasses ideal for front projection viewing. Sony TDG-PJ1 active 3D glasses are compatible with select 2014-up Sony ES 3D-ready front projectors; including the VPL-HW40ES and VPL-HW55ES (both sold separately).

Active Shutter Technology: When using the active shutter glasses, the on-screen image is precisely synchronized and delivered with the full high-definition image intact, for an optimum 3D viewing experience. Sony's 3D technology displays high speed synchronized left- and right-eye images to deliver an amazing 3D experience. And since each frame you see is shown in high-definition, the 3D action still offers razor-sharp detail.

IR Transmission: The 3D glasses operate by receiving infrared signals from the 3D Sync Transmitter of your Sony ES front projector. The 3D Sync Transmitter of your projector must be positioned so that you are facing the transmitter when wearing the 3D glasses. 

Rechargeable Battery: The Sony TDG-PJ1 active 3D glasses features a built-in rechargeable lithium-ion battery capable of 4 hours of use on a full 3 hour charge. A quick 3 minute charge provides approximately 3 hours of use. The built-in rechargeable battery simply charges via USB, using the included cable.
