Current-controlled precision vs budget three-nerve stimulation. Two ear-based approaches at different price points.
Vagally Understood
Vagal Buddy vs VeRelief
Both ear-based. One delivers current-controlled precision. The other claims three-nerve stimulation at a budget price.
Vagal Buddy
$349
VeRelief Prime
~$199
Current control
Current-controlled (tVNS)
EverSteady measures impedance 50,000 times per second. The current stays constant regardless of skin conditions. Published specification: 0.1–4.0 mA.
Current control
Not specified
VeRelief does not state whether it uses current-controlled or voltage-controlled output. Specifications focus on the three-nerve targeting claim rather than stimulation control method.
Stimulation target
Vagus nerve (auricular)
Targets the tragus of the ear, which has the most direct vagal pathway to the brainstem. Single-nerve, focused approach backed by 200+ published studies.
Stimulation target
Three nerves claimed
VeRelief claims to target the vagus, trigeminal, and median nerves simultaneously via behind-the-ear placement. Multi-nerve targeting has less published research than focused auricular tVNS.
Safety certification
IEC 60601-1, CE, FCC
International medical device safety standard. The same certification applied to equipment used in hospitals and clinical research.
Safety certification
General wellness
VeRelief is marketed as a general wellness product. IEC 60601-1 medical device certification is not listed in their published specifications.
Protocols
50+ updatable via app
Research-based protocols loaded through the Vagal Tones app. New protocols added as clinical research advances. Device improves over time.
Protocols
Built-in programmes
Pre-set stimulation programmes. Programme selection via the device. No app-based protocol updates.
Lower price point with three-nerve targeting. 30-day guarantee. Control method and medical device certification not specified.
Budget price, or controlled dose?
VeRelief Prime costs less and claims to target three nerves simultaneously. Vagal Buddy costs more but delivers a known, current-controlled dose with IEC 60601-1 medical device certification and updatable protocols. Multi-nerve targeting is a newer concept with less published evidence than focused auricular tVNS. The question is whether you want the lowest price or the most precisely controlled stimulation.

Comparing Vagus Nerve Stimulators
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.
