Due to increased stress and anxiety levels from the current demands of the world, the number of people suffering from headaches and migraines will only continue to rise. That is why Zōk was developed. It's a consumer-friendly, Class I medical device that naturally reduces tension and pressure inside the head. Zōk provides relief by stimulating the tympanic membrane, which activates the trigeminal nerve and a number of cranial nerves inside the head through inner-ear pressure modulation, thereby providing instant alleviation of pressure and tension inside the head, which are associated with the symptoms of headaches and migraines. Experience immediate relief — 100% natural and non-invasive!
