Razer's Project Carol is a product design concept for a head cushion with built-in peripherals. Features include a haptic feedback system for physical effects, 2.4 GHZ wireless design with up to 8 hours of battery life, and near-field surround sound to allow for a more immersive gaming experience. However, as Project Carol is a concept product, it may not be available for purchase and is still under development by Razer.
