Touted as the world’s most effective wearable for stress and sleep management, Kortex stimulates the brain to produce serotonin while lowering cortisol (the stress hormone) and may be used by itself or with a virtual reality headset. The device is designed to be attached to a headband and to most VR headsets, including the Samsung Gear VR and ZEISS VR ONE Plus (and excluding the Sony PlayStation VR). Relaxing, meditative and engaging VR content enhances the experience — and to that end, the company has partnered with ustwo games (the makers of Monument Valley) to provide every user with a free copy of Land’s End. Kortex consists from the base unit, two electrode clips, two electrode sponge caps, electrode sponges, wires, and a headband. A three-month supply of electrode sponges will be included with every kit, while additional sponges will be available for purchase at a reasonable price.
