When combined with Samsung 3D TVs, 3D Active Glasses bring viewing to vivid life. Samsung’s newest 3D Active Glasses offer even greater comfort over hours of viewing. Keep the 3D Active Glasses viewing-ready for family and friends with the Samsung Wireless Charging Hub (CY-SWC1000A) (sold separately) that recharges up to four pairs at a time, or charge with the included USB cable.
