ZenBud

ZenBud is a wearable, ear-mounted ultrasound device that gently stimulates the vagus nerve to help shift the body out of "fight-or-flight" and into a calmer, more regulated state, with no electrical current, no drugs, just a few minutes a session. It's designed to support stress relief, better sleep, and nervous system resilience, with early research pointing to improvements in heart rate variability and anxiety symptoms.
