Tired but wiredat 2am?
A small clip on your ear reaches your vagus nerve, the nerve that helps your body wind down. It checks its contact with your skin 50,000 times a second and holds the current steady, so the strength you choose is the strength you feel, every night.
Both hold the current steady. Oh! has no wire and runs from your phone. Buddy has a screen and a 4-hour battery.
No need to wait. If we lower a price within 14 days of your order, we refund the difference.
This week's extra: Nightshift Tone free with Buddy or Oh! (worth $39.00), until Sunday, November 1.
Try it for 45 days. Not for you? Post it back and we refund the full price you paid. The most a trial can cost you is the return postage, about $20 from the US. How returns work
- 45 days to try it
- Free standard shipping

Why your ear?
Your body has a brake
The vagus nerve is the main brake on your stress response. It is the nerve that lets you wind down.
Part of it reaches your ear
A small branch comes close to the skin at the tragus, the flap in front of your ear canal. That is where the clip sits.
Vagal keeps the signal steady
It checks its contact 50,000 times a second and holds the current you set, so tonight feels like last night.
Chosen by researchers at dozens of universities since 2019. Research Edition lets a lab set the current to the microamp and run sham sessions for blinded studies, on the same Buddy you can buy. See the research setup
Three Devices. One Goal.
Oh! and Buddy hold the current steady. Choose Oh! for no wire and the lower price, Buddy for a screen and long sessions, or Boost to try stimulation for $59.
18 grams, no wire, no screen. Current-controlled, like Buddy. Runs from your phone, about 60 minutes per charge (up to 4 sessions).
Screen and joystick, 4+ hours per charge, and it keeps running on its EverCharge pad, which is in the box.
Plugs into your phone (not Samsung). Voltage-controlled, like most clips: a low-cost way to feel stimulation.
“If it isn’t right for you, email me and I’ll sort it out.”
Hannah, Customer Support, at [email protected]. We are a small team in London and we answer our own emails. We started in 2019, when researchers asked us to build a better ear clip for a vagus nerve study.
Not for everyone. Do not use Vagal with a pacemaker or another implanted electronic device, in pregnancy, or if you are under 18. Ask your doctor first if you have a heart condition, have fainted or have low blood pressure, have epilepsy, or take regular medication. Who should not use Vagal
Why Buddy Is the One Most People Choose
The most popular tVNS device we make. 2nd generation vagus nerve stimulation: bigger where it matters, smarter where it counts.
Charge while you stimulate.
Buddy charges on its pad without a wire, so there is no electrical path from the wall to you. Put it on the pad and your session carries on.
4+ hours a charge. Two weeks of daily sessions.
A 540mAh battery gives over 4 hours of stimulation on one charge: about 16 daily 15-minute sessions before it needs the pad.
See more. Guess less.
A 30% larger OLED screen makes it easier to read session timers, adjust intensity, and navigate protocols at a glance.
Morning coffee to lights out.
Clip on during your commute, at your desk, on the sofa, or in bed. With EverCharge, your bedside table becomes a charging station, so Buddy is topped up and ready for tomorrow's session.
Same current-controlled EverSteady precision. Same Vagal Tones app. New everything else.
Meet Buddy,What Our Users Say
Verified reviews from Vagal device owners
Sleeping better than I have in years. I was sceptical but after two weeks of daily sessions, the difference in my sleep quality is undeniable. Worth every penny.
I'm obsessed with my Vagal Oh! I use it during my morning meditation, and it's like flipping a calmness switch. ... the design is so sleek, no one even knows I'm using it!
The Oh! is so easy to use. No cables, no fuss. I clip it on during my morning coffee and it has become part of my daily routine. My digestion has improved noticeably.
How do we compare?
We use current-controlled tVNS. Most competitors use voltage-controlled tENS. See the difference for yourself.

Start your day grounded, not reactive
Morning cortisol is natural. A short, low-intensity session before you leave bed gives your nervous system a quieter start to the day.
suggest you start with
"I clip it on while I have my morning coffee. By the time I leave for work, I feel like a different person."
Stay sharp without the jitters
A short session before focused work helps your nervous system settle into a calm, alert state, so it is easier to stay with one task.
deep work block
"I used to lose focus after an hour. Now I get deep work blocks of three hours without even noticing."
Recover from the morning, digest your lunch
The vagus nerve is part of how your body shifts from "fight or flight" into "rest and digest". A lunchtime session is a simple way to make lunch a real break, so the afternoon starts calmer.
during or after lunch
"The post-lunch crash used to wipe me out. Since using Vagal at lunchtime, I actually have energy for the afternoon."
Switch off properly for the first time in years
Most people carry their work stress into the evening without realising it. Their heart rate stays elevated, their jaw is clenched, their mind races. Vagal stimulation in the evening trains your body to actually downshift -- not just collapse on the sofa.
from alert to genuinely calm
"My partner noticed before I did. She said I seemed calmer in the evenings. Less snappy. More present."
Fall asleep faster. Stay asleep longer.
Your vagus nerve is the main brake on your body's stress response. A short session before bed helps your nervous system shift into rest mode, so winding down comes more easily.
20 minutes before bed
"I went from lying awake for an hour to being out in 15 minutes. My sleep score on my watch has gone through the roof."
