Razer is showing off another of its unique concepts at CES 2023. Dubbed Project Carol, this is an innovative head cushion for your gaming chair that offers near-field 7.1 channel surround sound and converts game sounds to haptic feedback in real-time. Project Carol does not require any expensive setup and can be easily enabled by just hooking up the cushion to a proprietary 2.4 GHz wireless dongle connected to the PC.
