Heart rate. Digestion. Inflammation. Sleep onset. Stress recovery. Your vagus nerve manages all of it -- it's the main line between your brain and your body.
When it's active and healthy, these systems tick along in the background. When it's sluggish -- from stress, ageing, illness, or just life -- things start to feel off. Sleep gets shallow. Stress sticks around. Your gut complains. Recovery takes longer.
The good news: a branch of this nerve surfaces in your ear. And decades of clinical research show that gentle electrical stimulation through that pathway can help wake it back up.
Your skin resistance changes constantly -- with temperature, hydration, stress, time of day. Most consumer stimulators are voltage-controlled, which means the actual current reaching your nerve fluctuates from session to session.
The tVNS Stimulator is current-controlled. It measures your skin impedance and adjusts its output 50,000 times per second to deliver a consistent, known signal -- the same delivery method used in published clinical research. Repeatable results, every session.
EverSteady current control: the engineering that makes the difference between a precise instrument and a rough estimate.
Everything ships together. Clip on, press the blue button, and you're running your first session in under two minutes.
Free Vagal Tones app (iOS/Android) gives access to expandable protocol library. Additional protocols optional, from $29.
Individual results vary. These are the areas where our users and the published research overlap most.
The most commonly mentioned improvement across our reviews. Users describe falling asleep faster, staying asleep longer, and waking feeling more rested. Research supports a link between vagal tone and sleep quality.
Many users report a noticeable drop in daily anxiety within weeks. The vagus nerve activates the parasympathetic response -- your body's built-in way to come down from stress.
The vagus nerve directly controls gut motility. Several reviewers describe digestive improvements as their primary result, particularly those dealing with stress-related disruption.
Users describe feeling more patient, less reactive, more like themselves. Research suggests vagus nerve stimulation may support emotional regulation through brain-body signalling.
Athletes and high-stress professionals use tVNS to support parasympathetic recovery. Heart rate variability (HRV) improvement is one of the most measurable outcomes in the literature.
No drugs, no dependency, no drowsiness. tVNS is well-tolerated across thousands of research participants. The stimulation works with your body's own systems.
Unedited excerpts. Rated 4.6 out of 5.
"I bought this on my GP's suggestion for irregular heartbeats. It's easy to set up and use with or without the phone app. I feel at ease knowing I can do something proactive. Great little piece of kit."
"As someone who has dealt with PTSD symptoms for years, this has been life-changing. My anxiety levels have decreased noticeably and I'm sleeping better than I have in years. It took about three weeks to start seeing significant improvements."
"I've had a digestive issue for 6 years. My gastroenterologist had no diagnosis. After lots of research I found Vagal and the Digestive protocol. After only 2 weeks my issue was resolved. I've sent one to both my brothers."
"Extremely helpful with some of my health issues including long COVID. Just today I got nauseous for some reason and a session while lying down listening to music made that go away. 312 sessions and counting."
"This little device has changed everything for me. I wake up numerous times during the night and have terrible trouble getting back to sleep. Now I'm asleep again quickly and for longer periods. I love it."
"Excellent results regarding decrease in anxiety and panic attacks, and decrease in dizziness associated with POTS. I've been so pleased I've referred three people to purchase the device."
Initially skeptical about the device, I purchased it to help with post-workout recovery and stress management. Now I'm completely convinced of its benefits. I use it after intense training sessions, and I've noticed faster recovery times and better sleep quality. It's also helped with my pre-competition anxiety - I feel more centered and focused. The device is sturdy enough to withstand my active lifestyle, and the battery life is ok. While the price point is relatively high, the benefits to my athletic performance and overall well-being make it a worthwhile investment.
After a car accident left me with chronic neck pain, I was desperate for alternatives to pain medication. This device has been a game-changer. While it hasn't eliminated my pain completely, it's made it much more manageable and I've been able to reduce my pain medication significantly. The best part is that it's non-invasive and has no side effects. I particularly appreciate how portable it is - I can use it while working at my computer or watching TV. The battery life is excellent, and it's intuitive to use. Worth every penny for the relief it provides.
I applied the paste to the electrodes of the cable and applied it to my ears and used it every day. From one day an error (too strong resistance) came out and the output stopped increasing. This may be the result of my not vigorously cleaning the electrodes of the cable. I've washed it many times, but it doesn't irritate me as easily as before. As a result of consulting with support, I was recommended to purchase a "cable" and purchased it. I shaved the downy hair on my earlobes and cleaned the sebum with alcohol. I tried it without the paste. At first, the meter did not rise, but I moved the stick to the right several times to increase the output. After that, when I was looking at the device for a short while, the output naturally increased and I felt a stimulus in my ears. Little by little, the stimulation got stronger, so I pushed the stick once to the left and started to move with just the right amount of stimulation. I need a little "trick" to use it. However, I was correct to replace the cable with a new one.
I had my VNS implant put in in maybe 5 ago. The amount of seizures I had started disappearing quickly. At that that time, I had maybe 3 seizures a month. They quickly started to decline. Again, I am sorry I can’t give you any numbers. but getting this implant put in my body is so helpful. I didn’t have one in July and I had one August. I feel like I did that to myself. I was the one who put pressure on my body. It wasn’t due to an action on to have it. That was my fault.
The tVNS works out of the box with a built-in default protocol. The Vagal Tones app adds specialised protocols designed around published research parameters -- and the library is growing.
Firmware updates arrive over the air. New protocols are added as the research evolves. What you buy today is not what you're stuck with tomorrow.
The Research Edition upgrade unlocks full parameter programming, data logging, sham mode for blinded studies, and custom protocol creation. Same hardware -- digital upgrade via the app.
Requires firmware 5.2+. $299. Instant digital delivery, no shipping.Transcutaneous vagus nerve stimulation targets the auricular branch of the vagus nerve -- accessible through the ear. Gentle electrical pulses travel to the brainstem, activating the parasympathetic nervous system and triggering a cascade of downstream effects: reduced inflammation, improved heart rate variability, better autonomic balance.
This mechanism has been explored in over 200 published papers across more than two decades of clinical research. The tVNS Stimulator uses the same current-controlled, biphasic square wave delivery method found in those studies.
