Compare Vagus Nerve Stimulators

Will this work for me? Will I get a consistent dose? What will it cost over time? The questions worth asking before you buy.

What actually matters when choosing a vagus nerve stimulator?

Most comparison sites focus on price. Price matters, but it's not the whole story. The questions worth asking: does the device deliver a consistent dose every session? Will it need gel, subscriptions, or expensive replacement parts? Can it be updated as the research evolves, or is the hardware frozen in time?

The biggest technical difference between devices is how they control current. Current-controlled stimulators (tVNS) maintain a steady therapeutic dose regardless of skin moisture, temperature, or contact pressure. Voltage-controlled stimulators (tENS) set a fixed voltage, but the actual current reaching the nerve fluctuates with conditions. That means the dose changes session to session — sometimes within a single session. Most comparison sites don't mention this. Learn more about current control.

Common questions

About vagus nerve stimulators, how they compare, and which is right for you

What should I look for when buying a vagus nerve stimulator?

The most important technical specification in a vagus nerve stimulator is the current control method. Current-controlled devices (tVNS) deliver a consistent therapeutic dose regardless of changing skin conditions. Voltage-controlled devices (tENS) apply a fixed voltage, meaning the actual current reaching the nerve fluctuates. Other key factors include the stimulation target (ear-based auricular stimulation has the widest body of published clinical research), ongoing costs (gel, subscriptions, electrode replacements), frequency range, safety certifications (IEC 60601-1 is the medical device standard), and the availability of a money-back trial period. Of the consumer devices available in 2026, Vagal Buddy and Vagal Oh! are the only affordable current-controlled ear-based stimulators with IEC 60601-1 certification.

Is Vagustim current-controlled?

Vagustim is an ear-based vagus nerve stimulation device that targets both ears simultaneously. Their published specifications do not state whether the device uses current-controlled or voltage-controlled output. Vagustim describes its stimulation as "gentle electrical impulses" with an "intelligent algorithm" that adjusts based on comfort feedback, but does not specify whether the output is regulated by current or voltage. Current-controlled devices explicitly state this in their specifications because it is a significant clinical advantage. The Vagal Buddy ($349) and Oh! ($499) both use current-controlled stimulation via the EverSteady platform, with real-time impedance monitoring at 50,000 adjustments per second.

Is Sensate a vagus nerve stimulator?

Sensate is not a vagus nerve stimulator. It uses infrasound vibration on the chest, which is a fundamentally different technology from transcutaneous vagus nerve stimulation (tVNS). Sensate does not deliver electrical stimulation to the vagus nerve. It produces low-frequency vibrations intended to promote relaxation through a different mechanism. Vagal devices use electrical stimulation through ear electrodes to directly activate the auricular branch of the vagus nerve, which is the approach supported by over 200 published clinical tVNS studies.

Does Pulsetto need gel or a subscription?

Pulsetto requires conductive gel applied to the neck electrodes before every session. The gel tubes need regular replacement, adding an ongoing cost to the device. Pulsetto also offers a premium app subscription that unlocks additional programs beyond the free tier. By comparison, Vagal ear-based stimulators do not require gel (a small amount of conductive paste is optional for comfort but not required for operation), and there are no subscription fees for any Vagal device.

Is Nurosym current-controlled or voltage-controlled?

Nurosym (sold as Nuropod in the US) uses voltage-controlled stimulation (tENS), despite marketing itself as a tVNS device. The device applies a fixed voltage through ear electrodes, meaning the current delivered to the vagus nerve varies with skin conditions throughout each session. At approximately $699, it is the most expensive consumer ear-based stimulator available, yet uses the same voltage-controlled approach as the $59 Vagal Boost. Vagal Buddy ($349) and Vagal Oh! ($499) both use current-controlled stimulation via the EverSteady platform, delivering a consistent dose at less than half the price of Nurosym.

Is Pulsetto current-controlled or voltage-controlled?

Pulsetto uses voltage-controlled stimulation (tENS), not current-controlled stimulation (tVNS). This means Pulsetto applies a fixed voltage, and the actual current reaching the vagus nerve fluctuates as skin moisture, temperature, and contact pressure change during a session. Current-controlled devices like the Vagal Buddy ($349) and Vagal Oh! ($499) measure skin impedance in real time and adjust output to maintain a constant current. Current-controlled stimulation is the method used in the majority of published clinical tVNS research because it delivers a reproducible dose.

What is the difference between the Vagal tVNS Stimulator and the Nemos tVNS?

Very little, technically. Both are current-controlled tVNS devices — unlike most consumer devices on the market, which use voltage-controlled tENS. Both use titanium electrodes for biocompatibility. Both support doctor-created stimulation protocols. And both log actual current delivered per session, giving users and clinicians a clear treatment record. The Nemos (by tVNS Technologies GmbH, formerly Cerbomed) pioneered non-invasive auricular vagus nerve stimulation and has been used in clinical research since 2012. It is a Class IIa medical device approved under EU-MDR for epilepsy, depression, and migraine. The Vagal tVNS Stimulator was built on the same current-controlled principles. The main differences are price and availability: the Nemos retails at approximately €3,500 and requires a doctor's authorisation, available only in parts of Europe. The Vagal tVNS is $399 and ships worldwide with no prescription required. See the full side-by-side comparison.

Is Nuropod the same as Nurosym?

Nuropod is the US brand name for Nurosym, both made by Parasym. It's the same device and the same technology — voltage-controlled electrical stimulation (tENS) delivered through the ear. The name difference is purely regional branding. Everything in our Vagal vs Nurosym comparison applies equally to Nuropod. Nuropod and Nurosym are trademarks of Parasym Ltd.

What is the difference between Pulsetto and Nurosym?

Both Pulsetto and Nurosym use voltage-controlled stimulation (tENS), which means the actual current reaching the nerve varies with skin conditions. Pulsetto targets the neck and costs approximately $269 but requires conductive gel each session. Nurosym targets the ear and costs approximately $699 with no gel required. Neither device offers current-controlled output (tVNS), which delivers a consistent therapeutic dose regardless of skin impedance. See our full Pulsetto vs Nurosym comparison. If consistent dosing is important to you, the Vagal tVNS Stimulator and Vagal Oh! both use current-controlled stimulation. Pulsetto is a trademark of Pulsetto UAB. Nurosym is a trademark of Parasym Ltd.

Which Vagal device should I start with?

It depends on what matters most to you. If you want the lowest-cost entry point, Boost ($59) uses voltage-controlled stimulation (tENS) and is powered by your phone — a great way to try vagus nerve stimulation. If you want current-controlled accuracy and updatable protocols, the tVNS Stimulator ($299) is the most popular choice and the device clinicians and researchers use. If you want wireless freedom in the smallest possible form factor, Oh! ($599) is the world's smallest wireless vagus nerve stimulator at just 23mm. All three stimulate through the ear and come with a 45-day money-back guarantee. See the Boost vs tVNS comparison or visit all comparisons.
