SOND Dreambuds: First AI Sleep Coach with Smart ANC

Your Personal Sleep Concierge

SOND Dreambuds are the first AI-powered earbuds built to actually improve your sleep—not just track it. Fully standalone and phone-free, they deliver real-time coaching, personalized soundscapes, and biometric insights based on 12 physiological signals—including cardio-respiratory coupling. SOND learns how you feel, adapts in the moment, and helps you fall asleep faster, stay asleep longer, and wake up clearer, calmer, and more in control.

 AI Coach That Guides You in Real Time

Meet your personal sleep coach.

SOND’s built-in AI assistant is designed to give you truly restful nights—not by showing you data, but by helping you sleep better in real time.  It delivers precisely timed audio interventions while you rest, learns your patterns, adapts each night, and supports you when it matters most—like after a stressful day or a 2 AM wake-up. Because sleep isn’t about tracking, it’s about getting help when you actually need it.

Sleep Without Screens, Phones, or Pings

Forget screen glow and distractions.

Unlike other earbuds, SOND delivers dynamic content, real-time sleep guidance, and AI-powered insights—all without needing to connect to your phone. Once connected to WiFi, everything happens in-ear—via voice or case controls. 
With 500+ ​​scientifically crafted tracks—meditations, ASMR, soundscapes—and AI that personalizes your sleep playlist nightly from sensor data, you just rest. No searching. No screen. Just sleep.

Sleep in Comfort—Even on Your Side

Comfort isn’t a feature—it’s a necessity. 

At just 3.3g, Dreambuds are designed to disappear in your ear—even if you sleep on your side. We developed a patented Tranquilock™ fit system, created specifically to support all ear shapes with zero pressure points. It combines three sizes of soft, medical-grade silicone tips with three retention styles to ensure a secure, pain-free fit.

The body is crafted from lightweight, skin-safe PC-ABS plastic, so you can sleep without pressure and pain.

 Smart Alarm With Gentle, Timed Wakeups

Falling asleep is only half the story. To wake up fully energized, timing is everything. Dreambuds’ Smart Alarm tracks your sleep and offers three wake modes—whether you want to feel refreshed, wake up at a specific time, or even remember your dreams. Just choose your preferred mode in the app, and let the AI handle the rest.

Premium Sound That Calms the Mind

With premium wide-frequency drivers and richly layered soundscapes, SOND Dreambuds don’t just play audio—they place you inside it. Be surrounded by rolling waves. Lie beneath a canopy of trees. Float in weightless silence among the stars. With over 500 scientifically crafted tracks, every sound is designed to quiet your mind and relax your body. Don’t be surprised if they become your go-to earbuds—day or night.

More Than Sleep. A Window Into Your Health

SOND looks beyond how you sleep.
It passively tracks your heart and breathing health while you rest—no wires, no wearables. Using embedded sensors, it can detect early signs of irregularities like atrial fibrillation, abnormal breathing, or elevated resting heart rate. If something stands out, SOND flags it gently—helping you stay informed without ever disrupting your night.
It’s not just about sleep improvement—it’s peace of mind.

Your Sleep, Explained in One Smart App

The SOND app is your personal sleep dashboard. It stores your nightly data, dream logs, and AI recommendations—all in one intuitive place. 
Track your trends, see what’s working, and get smarter about your sleep over time.

 About us

SOND was founded in 2022 by MIT graduates Yadid Ayzenberg (PhD) and Amir Lazarovich (MSc), driven by frustration with sleep products that only track, but never help. Yadid’s work in wearable sensors and closed-loop interventions led to a generative audio platform later acquired by Bose—where he spent years advancing sleep technology. Amir brought deep tech experience from Google. Together, they built SOND: the world’s first AI-powered dreambuds that not only track your sleep, but  transform it.
