What does tVNS feel like?
It feels like a little tingle on your ear. Some people say it is like a tickle, some like a peck.
The clip also applies a little pressure to the tragus, which to date two people have found to be too uncomfortable to wear.

Frequency of use – can I use more than 15 minutes per day?
Yes. Many studies use stimulation durations of up to several hours per day.
Can I Wear a Hearing Aid When Using tVNS
You should remove your hearing aid before using tVNS. If you have an implanted hearing device then you should not use tVNS.
Does vagus nerve stimulation help relieve tinnitus?
Yes, there is some early data showing that tVNS can reduce the severity of tinnitus.
Where is the Vagus Nerve Stimulated?
The Vagus nerve is named after the greek word meaning “wander”. This is because anatomical studies revealed that it travels a wide path throughout the human body. From the stomach, lungs, heart and brain but also to the ears. So the easiest location to stimulate the Vagus Nerve happens to be in the ear. Specifically the tragus of the left ear.
What is the difference between tVNS and VNS?
The “t” stands for transcutaneous meaning through the skin and this is the key difference. VNS devices are implanted inside the body whereas tVNS devices are not, because they operate through the skin.
I can’t feel anything
When using the device with the supplied conductive paste, you may feel very little or nothing at all from the stimulation. This is perfectly normal.
If you are unsure, try using the device without the conductive paste. You should feel a tingling or prickly sensation, which some people find unpleasant. The conductive paste is included to make stimulation more comfortable.
If you do feel something, this will be a result of activation of the sensory receptors in your skin. It actually has nothing to do with stimulation of the vagus nerve, which runs below the skin.
Your skin contains receptors for pain, pressure and temperature. What or how much you feel (with or without paste) is dependent on a number of factors including your skin type and sensitivity. Most scientific and clinical studies which investigate the benefits of tVNS will set the stimulation intensity to a level that is completely (or almost completely) imperceptible.
The device itself measures the flow of current. If no current is flowing this will be indicated.
If you prefer to feel something, use the device without conductive paste (or with very little) and set the intensity to a level that you can tolerate. You may find that after some time, your skin becomes accustomed to the sensation and can tolerate an increased intensity. You should set the level to the maximum you can tolerate without feeling discomfort.
