Vagustim is the world's most studied bilateral vagus activation device. Both devices aim to support stress regulation and recovery; they differ in where they are worn, what they need every session, and how much research sits behind the device itself.
Most decisions come down to three things. This is where the distinction between the two devices becomes clear.
The location of vagal stimulation determines which nerve fibers are reached and how directly. Ear-based and neck based stimulation work very differently at the anatomical level.
Preset programs work for casual use. But if you plan to use VNS consistently, the ability to adjust stimulation parameters over time makes a meaningful difference to your results.
For users who value evidence-based tools, understanding how a device's approach is documented in published research is one of the most important things to look at before deciding.
Every meaningful specification, compared directly.

The stimulation site impacts how directly the vagus nerve is reached and ultimately how the experience feels.
Vagustim targets the auricular branch of the vagus nerve through the ear. This area gives more direct access to vagal nerve fibers at the skin surface, which is why it is widely used in research.
Pulsetto stimulates through the neck near the cervical branch of the vagus nerve. This area lies deeper under tissue.
A stronger foundation for people who care about evidence, consistency, and measurable progress.
More than presets Vagustim is built for users who want flexibility, personalization, and progress.
Adjusts sessions based on goals and feedback.
Built around the most studied stimulation pathway.
Customize pulse, frequency, timing.
Works fully offline anytime.
Both devices support the nervous system. The difference is how deeply you engage.

The questions most people ask before choosing between the two devices.
Most vagus nerve research uses ear-based devices, because the ear is the one place where a branch of the vagus nerve reaches the skin surface. Vagustim works on both ears in the same session.
Yes. Pulsetto asks you to apply conductive gel on the neck before each session. Vagustim needs no gel.
Pulsetto's core app is free. Its Premium app costs $45 every three months. Vagustim works offline with on-device buttons, so no subscription is needed.
Yes. Vagustim has a 30-day money-back guarantee and a 2-year warranty.
It depends on what you value. Pulsetto offers short neck-worn sessions. Vagustim is worn in both ears, needs no gel, and is the world's most studied bilateral vagus activation device, with 60+ published studies.
Vagustim uses ear-based stimulation with adjustable settings and AI personalization. Pulsetto uses neck-based stimulation with preset programs.
Yes. Vagustim is designed around research-backed auricular stimulation and flexible device control.
Vagustim offers more manual control, including adjustable parameters such as pulse, frequency, and timing.
Yes. Ear-based and neck-based stimulation reach different areas and can create a different user experience.
No. Vagustim works offline with on-device buttons, so no subscription is needed.
Vagustim has a 2-year warranty and a 30-day money-back guarantee.
Vagustim is positioned for users who want long-term flexibility, personalization, and progress tracking.
