Frequently asked questions

When will I see results?

A majority of users experience noticeable improvements in mood and sleep within 7 days. However, individual sensitivity to vagus nerve stimulation varies, and those who are less sensitive may require a longer period to observe significant effects.
How often and how long should I use it?
  • For users experiencing mild anxiety or sleep disturbances, we recommend one full 20-minutes session daily.
  • For those with more pronounced symptoms, two full 20-minutes sessions (totaling 40 minutes) per day are suggested.
  • For optimal results, consistent daily use is recommended. Noticeable improvement is typically observed after 4 weeks of continued use.
Is it safe?

The WONZ ta-VNS Device utilizes non-invasive technology. Simply wear the auricular electrode in your ear, just like putting on an earphone. Across all usage modes, it offers 30 adjustable intensity levels, allowing you to find the most comfortable setting based on your sensitivity to microcurrents. The product leaves no side effects and causes no dependency after use.
