This is the mount and wireless headphones that convert an iPad into a backseat theater. The sturdy plastic mount clamps firmly to the back of any auto headrest, holding an iPad securely with padded spring clips that leave the device's ports and buttons accessible. The mount pivots 90º and tilts 25º on a gooseneck to let you achieve an optimal viewing position. Audio is transmitted over an FM radio frequency (but won't interfere with the car's radio operation) to two included wireless headphones. The transmitter plugs into an iPad's headphone jack and a car's 12-volt DC socket, and charges the iPad. Each headset requires two AAA batteries. Holds tablets from 8 1/2" H x 6 1/2" W to 10 1/2" H x 7 3/4" W. 5" H x 5" W x 3 1/2" D. (1 lb.)
