Vagal Buddy vs Nurosym
Same goal. Same ear-based approach. Six differences that matter.
Vagal Buddy
$349
Nurosym
~$699
Stimulation type
Current-controlled (tVNS)
EverSteady adjusts in real time. The current stays constant regardless of changing skin impedance. The dose you set is the dose delivered.
Stimulation type
Voltage-controlled (tENS)
The voltage stays fixed but the current fluctuates as skin moisture, temperature and contact pressure change.
Stimulation protocols
Multiple, updatable via app
New protocols loaded through the Vagal Tones app as research advances. Your device evolves without replacing hardware.
Stimulation protocols
Fixed
One stimulation protocol. No app-based updates to parameters.
Ongoing costs
Earpiece replacement over time
No gel, no subscription. The ear clip will eventually need replacing with regular use; affordable replacements are available in our store.
Ongoing costs
Earpiece replacement over time
No gel or subscription. 6-month warranty on earpiece electrodes. Replacements available at additional cost.
Ease of use
Display + joystick
A clear on-device display shows your session settings at a glance. The joystick lets you adjust intensity mid-session without fiddling with buttons.
Ease of use
Single button + LED
Intensity adjusted by pressing a button repeatedly. A small LED indicates status but doesn't show settings.

Same ear. Different technology. Half the price.
Both devices target the vagus nerve through the ear. Vagal Buddy uses current-controlled stimulation for a consistent dose every session. Nurosym uses voltage-controlled tENS, where the dose fluctuates with your skin. Buddy costs half the price, includes EverCharge wireless charging, and comes with a 45-night sleep trial.
