Xen’s electrical signal is usually described as tingling or tickling in the ear. The intensity can be adjusted up or down during your session, to your comfort level. Some Xen users describe a calm feeling within minutes of starting a session, and the calmness can last a half hour or more after the session ends. Many users find that daily use over a period of several weeks promotes a stronger sense of wellbeing.
Please note that it isn’t necessary to feel the signal to experience the benefits. In fact, much of today’s tVNS research has been done at a level just below what people can feel. One way to achieve this is to increase the intensity to a level where you feel the stimulation and then leave it at that point or reduce it to just below that level.
