Watch all of your movies on the go with the CinemizerOLED Video Glasses. This headset was designed by Zeiss and uses Zeiss Optics. It's equipped with dual OLED displays that simulate a 40-inch screen being viewed from approximately 6' away. It accepts video from HDMI and AV sources, as well as select Apple devices (required adapter sold separately). Built-in speakers allow you to enjoy your content in stereo sound with the included headphones. In case you wear eyeglasses, you can still enjoy movies on the CinemizerOLED, as it can be configured for prescriptions ranging from -5 to +2 diopters in each eye. The CinemizerOLED comes equipped with an integrated rechargeable battery for up to six continuous hours of use.
