Reset Your Stress
Feeling exhausted throughout the day, even though you got plenty of sleep? It's not just you. So many of us feel overwhelmed in the stress of the day-to-day.
The good news is that it's easier than you think to get that much-needed relaxation. Introducing BeCozU — your personal taVNS wearable. Just insert this wearable into your ears to embark on a relaxation journey. All it takes is 15–30 minutes before bed or during your lunch break.
What does taVNS feel like? A gentle flow of energy in your left ear that helps you reset stress and relax like never before.
Next Level Rest & Relaxation
Meet BeCozU — a high-tech wearable that sends a pulse through the vagus nerve in your ear. Though the pulse itself is weak, it comes with powerful effects.
Instant Relief
Using taVNS technology, BeCozU sends a weak pulse through the ear to stimulate the vagus nerve — creating an instant anxiety and stress relieving effect.
Comfortable In-Ear Design
Shaped as a convenient in-ear insert with a speaker component. Whenever you're ready to unwind, just take BeCozU out of the charging case and start your relaxation journey.
Unwind, Any Time of Day
Think of BeCozU like a gentle tap of energy that lets you better unwind at the end of your day — or a revitalizing power nap in the middle of it, letting you tackle whatever comes next.
Quick 30-Minute Sessions
After just a quick 30-minute session, BeCozU helps you flush out all the distractions keeping you away from what's really important.
10 Customizable Levels
With 10 customizable intensity levels, BeCozU lets you find which setting gives you the best personal results.
Soothing Music Built In
There's a library of soothing music you can listen to for added relaxation. Or, if you'd rather listen to your own Spotify playlist instead, BeCozU lets you do that too.
