Experience virtual reality firsthand with the I AM CARDBOARD DSCVR headset. They are, among others, certified by Google. The 34mm biconvex lenses guarantee a sharp display. The headset is also large enough to accommodated a wide range of smartphones — even the Nexus 6 and iPhone 6 Plus. There's no need to worry about the size of your phone with this headset! The control button is the same as that on Google Cardboard V2. The glasses are equipped with a silicone flap that prevents your phone from slipping or falling.
