Ear vs Neck VNS Devices: An Overview

Ear VNS Devices: Stimulation at the Tragus

Ear VNS devices send gentle electrical pulses through a small earpiece on the outer ear. Many target the tragus, the small flap of cartilage just in front of the ear canal, where the vagus nerve reaches the skin of the ear. The nerve fibres sit close to the surface there, so the signal only has to cross a thin layer of skin, and a low-intensity current is designed to reach them. 

Placing an electrode on the ear does not make two devices alike, though. An ear device's performance depends on the exact site it stimulates, the waveform it delivers, and how its sessions are structured over time.

Nurosym’s earpiece clips onto the tragus and delivers AVNT, Parasym’s proprietary waveform, at that defined site. The earpiece is designed to return to the same position every session. Sessions run for 15 to 30 minutes, once or twice a day, at a gentle intensity, often during desk work, reading, or an evening at home. 

Nurosym clips onto the tragus and stays in place hands-free, with no gel or app needed. 

Neck VNS Devices: Stimulation Through the Neck

Neck VNS devices place electrodes on the side of the neck, over the vagus nerve as it runs alongside the carotid artery. At that point, the nerve lies beneath skin, fat, and muscle, so surface pulses must pass through deeper, more complex tissue to reach it. 

The amount of signal that actually reaches the nerve varies from person to person. It depends on how precisely the device is positioned, how evenly the electrodes sit against the skin, the stimulation intensity, and the natural shape of each person’s neck.

Conductive gel or spray helps the current cross the skin at these contact points, so it is a practical need created by the site itself. Truvaga and gammaCore, both made by electroCore, are handheld units pressed against the neck for the length of each session. Pulsetto works differently. It wraps around the neck as a band and runs short sessions through its app.

The neck has a long history in VNS through implanted systems, where surgeons place electrodes directly on the nerve. Non-invasive neck devices work from outside the body, so they lack that direct contact and depend on reaching the nerve through the tissue above it.

What Each Device Costs to Own

Ear VNS Device Costs

Nurosym costs €700 (~$785) as a one-time purchase, with free shipping included. The kit includes the device, earpiece, charger, quick start guide, and case, with no monthly fees, gel, or paid app subscription. Nurosym also comes with a 30-day return guarantee.*

Neck VNS Device Costs

Truvaga Plus costs $499, or as little as $46 a month on a payment plan, and Truvaga 350 costs $325, or as little as $31 a month. Both models need a conductive medium on the skin. Truvaga sells its Signagel electrode gel and Signaspray solution at $45 per six-pack, so refills become a regular cost for daily users.

Pulsetto FIT is listed at a $296 sale price and Pulsetto Lite at $269. Each device ships with a 60g gel tube that the brand describes as a 30-day supply. The free app includes five programmes, and Premium continues at $45 per quarter after the free trial unless you cancel.

gammaCore is a CE-marked medical device in the EU and UK. In the US, it is prescription-only and ordered through a form completed by a healthcare provider, so it has no public shop price there and cannot be compared directly with the other devices here. 

What's the Difference Between Ear & Neck Devices?

Stimulation Site & Directness

The core difference is how directly each device reaches the vagus nerve. At the tragus, the signal crosses a thin layer of skin to reach nerve fibres near the surface. At the neck, the same signal must first travel through skin, fat, and muscle, so it depends more on intensity and contact. 

A stronger sensation at the neck doesn’t mean the nerve is being reached more precisely. 

Placement Consistency

Nurosym’s earpiece rests on the tragus, and the ear’s shape is designed to hold it in the same place each time, so each session targets the same spot as the one before. That consistency matters for a routine built on daily use. Neck devices depend on the user finding the right spot again at each session. 

A handheld unit such as Truvaga or gammaCore moves with the hand holding it, and a band such as Pulsetto can sit slightly differently with each fit, so skin contact can vary from one session to the next.

Session Length & Intensity

The two routes also lead to different session designs. Nurosym is designed for structured daily use, with sessions of 15 to 30 minutes, once or twice a day, based on protocols studied in Parasym’s clinical research. This recommended length is not the minimum time in which an effect has been measured. 

Measurable effects have been observed in much shorter sessions of around 4 minutes. Stimulation is delivered at the tragus, where the ear branch of the vagus nerve lies close to the skin, so Nurosym uses gentle electrical pulses at a defined, consistent level. Because it is wearable and hands-free, a session fits around working, reading or resting.

Neck devices work differently. To reach the vagus nerve in the neck, the signal must travel through the skin and deeper, more anatomically complex tissue. This makes consistent targeting more difficult and can mean higher stimulation outputs are needed. Sessions also tend to be short and self-guided. 

Pulsetto runs brief programmes through its app, with several programmes and adjustable intensity settings, so the stimulation is not standardised and can vary from user to user and from session to session. Truvaga and gammaCore sessions last only as long as the user holds the device against the neck. Both require manual positioning each time, making consistency more dependent on user technique and individual neck anatomy.

Clinical Backing

The research gap between the two groups is wide. Parasym’s AVNT technology has been tested in 60+ completed clinical studies.* Studies are independently designed, led, and interpreted by outside investigators at partner institutions, with Parasym providing the device and technical support only. That research uses Parasym’s technology at the tragus, the same site Nurosym stimulates. 

Truvaga has no published trials of its own device, and Pulsetto’s studies are largely small, industry-funded pilots. Much of what is said about both therefore relies on general neck VNS research, not on evidence about the products themselves.

gammaCore does have clinical studies, but they focus on migraine and cluster headache. Those results don’t apply to Truvaga, even though both devices come from electroCore and share the same technology.

Regulatory Status

Nurosym is a CE-marked medical device in the EU and UK, classified as Class IIa. It is used alongside existing care, not in place of it.

gammaCore is a CE-marked medical device in the EU and UK, and its clinical evidence focuses on migraine and cluster headache. In the US, it is FDA-cleared and prescription-only for certain headache types. Anyone living with a headache condition should speak with a healthcare professional about suitable options. 

Truvaga and Pulsetto describe their devices as general wellness products not intended for any disease or condition.

Gel, App & Hands-Free Use

Setup needs such as gel and apps follow from placement. Nurosym needs no gel, starts with the device itself without an app, and stays hands-free on the ear. Neck devices need gel or spray on the skin before each session to help the current reach deeper tissue. 

Truvaga and gammaCore must be held against the neck throughout. Pulsetto’s band leaves the hands free but needs its app to run, and its fuller set of programmes sits behind the paid Premium tier.

Safety & Side Effects

Nurosym’s technology has demonstrated a strong safety profile, with no device-related serious adverse events reported to date. In a safety review across several studies involving over 200 participants, only three participants (1.5%) reported minor effects, limited to brief tingling sensations at the ear. 

Individual suitability still matters, particularly for people with implanted electrical devices, significant cardiovascular conditions or other circumstances covered by the device contraindications. As safety has not been established across all populations, Nurosym is not recommended for children or during pregnancy.

gammaCore has been clinically evaluated, with mild side effects such as discomfort and dizziness reported. Pulsetto is marketed as well tolerated but is contraindicated for people with cardiac arrhythmia, tachycardia, an abnormal ECG or prolonged QT, cardiovascular disease, and uncontrolled blood pressure. Truvaga users generally report mild sensations typical of electrical stimulation. 

Benefits of Each VNS Device Placement

Benefits of Ear VNS Devices

Ear stimulation on its own isn’t the difference; what matters is whether stimulation is delivered through a defined, tested, and repeatable system. Nurosym stimulates at the tragus, where a gentle current is designed to reach nerve fibres near the surface, and its earpiece returns to the same spot to keep each day’s session consistent with the last. That combination supports longer daily sessions that run in the background, with no gel or app to manage. 

Nurosym also gives buyers a method backed by research on its own technology. Nurosym is the most studied wearable vagus nerve stimulation device. Its evidence base was built over 10+ years of research and development with 150+ research partners, and several studies are peer-reviewed and freely readable in full text on the evidence page.* 

Nurosym stays on the ear hands-free, with no gel or app required, and its technology has been tested in randomised, placebo controlled studies.* 

Benefits of Neck VNS Devices

The main benefit of neck VNS devices is a short session with a clear start and finish, which suits people who prefer a quick, guided routine. Pulsetto leans into this. The brand markets its sessions as taking around four minutes, keeps five programmes free after any Premium trial ends, and syncs with Apple Health and wearables such as Garmin, Whoop, and Oura.

Truvaga offers two price points, with the 350 model as a simpler, lower-cost option. The brand markets both devices as general wellness products for relaxation, focus, and sleep.

gammaCore is the only device here tied to a prescription pathway. This makes it a different kind of purchase, designed for people whose healthcare provider has recommended it for migraine or cluster headache.

Ear vs Neck VNS Device: Comparison Table

Choose Hands-Free Ear Stimulation With Nurosym

Ear and neck devices target the same nerve, but reach it in very different ways. Ear stimulation reaches the vagus nerve close to the skin, while neck stimulation must pass through deeper tissue. Positioning, contact, and anatomy therefore matter more at every neck session, and the need for gel, with its running cost, follows from that choice of site. 

Nurosym is built for people who want stimulation at a defined site on the ear, delivered the same way every session. Its earpiece is designed to rest on the tragus, where the vagus nerve reaches the skin of the ear, and to deliver Parasym’s AVNT waveform to the same spot every day. Start using Nurosym at home alongside your existing care. 

Frequently Asked Questions (FAQs)

Is ear or neck vagus nerve stimulation better?

Neither placement is a direct substitute for the other, because each reaches the vagus nerve in a different way. Nurosym stimulates at the tragus, where the vagus nerve lies close to the skin. Neck devices work through deeper tissue and suit short sessions, while gammaCore’s evidence focuses on headache conditions. 

Which of these devices are medical devices?

Of the devices covered here, Nurosym and gammaCore are CE-marked medical devices in the EU and UK. gammaCore’s evidence focuses on migraine and cluster headache, and in the US it is prescription-only. Truvaga and Pulsetto are sold directly to buyers as general wellness products. 

What is the main comfort difference?

The biggest comfort difference is whether your hands stay free during a session. Nurosym clips onto the ear and stays in place on its own, and Pulsetto sits around the neck as a band. Truvaga and gammaCore are handheld, so you must hold them against your neck throughout each session.

Which VNS devices have the most clinical research behind them?

Nurosym is the most studied wearable vagus nerve stimulation device. Parasym’s AVNT technology has been tested in 60+ completed clinical studies, with 100+ ongoing clinical studies underway.* Among the neck devices, gammaCore’s research focuses on headache conditions, Truvaga has no published trials of its own device, and Pulsetto’s studies are mostly small industry-funded pilots.
