Vagal vs Sensate Comparison

Two Vagal devices compared with Sensate. Electrical nerve stimulation vs infrasound chest vibration.

Vagally Curious?

Vagal Oh! vs Sensate

Both wireless. Both daily wellness tools. One sends electrical signals to your vagus nerve. The other vibrates on your chest.

How it works
Current-controlled tVNS
Sends precise, current-controlled electrical impulses through the ear directly to the vagus nerve. The method used in clinical research.
How it works
Infrasound vibration
Emits low-frequency vibrations on the chest, paired with soundscapes via an app. Not electrical nerve stimulation.
Size
23mm — fits in your ear
The world's smallest wireless VNS. Wear it anywhere. Nobody notices.
Size
Pebble-sized chest device
Placed on sternum or worn on a lanyard. Requires lying down or sitting still for best results.
Ongoing costs
None
Full app access. All protocols. No extra charges.
Ongoing costs
$100/year for full soundscapes
Free tier has limited content. Sensate Plus subscription unlocks the full library.
Dose consistency
Constant — adjusts to your skin
EverSteady current control delivers the same therapeutic dose every session, regardless of conditions.
Dose consistency
Fixed vibration intensity
Vibration is not electrically calibrated. Soundscape selection is the primary way to vary the experience.

Stimulation, not vibration.

Oh! delivers the same type of vagus nerve stimulation used in clinical studies — wirelessly, from a device smaller than a coin.

Based on publicly available specifications as of March 2026. Prices approximate and may vary. Sensate uses infrasound vibration, which is a different technology to transcutaneous vagus nerve stimulation (tVNS). Both approaches aim to support vagal tone through different mechanisms.
