Whether you’re winding down for sleep, taking a mindful break, or simply need a moment of relaxation—just wear blissol for 30 minutes.

It delivers a gentle 0.5Hz signal using ultra-low frequency synchronization technology to support deeper relaxation over time.
Weighing just 33g, blissol is soft, seamless, and designed to move with you—so you can relax anytime, anywhere.

Rest isn’t just about falling asleep—it’s about staying asleep.
During deep sleep, your brain naturally shifts into Delta wave activity (0.5–4 Hz), which is closely linked to physical and mental recovery.

blissol supports this process through patented synchronization technology that gently guides your brain into stable Delta wave patterns.
Its precisely calibrated 0.5Hz signal harmonizes with your brain’s rhythms, helping to ease tension and promote a grounded, restful state—without overstimulation.

Like tuning a string to the perfect pitch, blissol helps restore deep, authentic calm—anytime, anywhere.

Note: blissol is not a medical device and is not intended to diagnose, treat, or cure any condition. Please consult a healthcare professional for any medical concerns.

What sets blissol apart is its ability to deliver ultra-precise calming signals directly and effectively.
Unlike typical CES devices, blissol’s patent-pending technology enhances signal transmission to the body—maximizing effectiveness.

Its subtle 0.5Hz signal is calibrated to resonate with your natural brainwave frequencies, promoting a sense of calm without overstimulation or mental fatigue.

This deep alignment supports authentic rest—like tuning your body back to balance.

blissol was built on real science and real feedback.
To validate its effects, we conducted third-party sleep quality tests in partnership with a major university hospital in Korea—an institution known for its high research standards.

The results? In just 30 minutes, users showed improved balance between light and deep sleep, based on real-time data from smart devices. Our journey of innovation was recognized by CES, but we’re not stopping there.

Take a closer look at how blissol works, and join us in making true rest accessible for all.

Just 30 minutes a day with blissol made a measurable difference—reflected clearly in real sleep scores.
One user’s sleep score improved from 59 to 87 in just one week, based on data tracked through a smartphone app.

It’s not just about how long you sleep—it’s about how well. Users reported a more balanced ratio of light and deep sleep, and nights that felt calmer, deeper, and more restorative.

We also developed a free companion app, sleepisol bio, designed to work seamlessly with blissol. Use it to monitor your sleep patterns and track your progress—all in one place!

Relaxation shouldn’t stay at home. Whether you’re on a plane, in a hotel, or between meetings, blissol helps you reset—anytime, anywhere.

It weighs just 0.07 lbs (33g) and comes in a sleek, travel-ready pouch.
Light, discreet, and always within reach, blissol fits into any bag—so peace of mind is never out of reach.

Just slide the button and place blissol on your head. That’s it. Whether you’re reading, resting, or taking a break, it gently guides your mind into a calmer state—with zero effort.

Use it for 30 minutes, twice a day—and feel the difference in just a week. It’s not just for sleep. blissol works whenever you need deep, quiet rest.

Pro tip:Smartphones disrupt brainwave balance. For best results, try 30 minutes of screen-free calm during your session.

We focused on making blissol as intuitive and low-maintenance as possible.
That’s why it runs on a replaceable AAAA battery—no charging required.

As a special perk for our Kickstarter backers, we’ve included a custom opener so you can easily replace the battery and enjoy blissol even longer, wherever you are.

blissol is thoughtfully designed with the perfect balance of flexibility and durability, so it maintains its shape even with repeated use in various environments.

Crafted from a material that bends gently without breaking, it’s safe to use anytime, anywhere—giving you peace of mind in your everyday routine.

blissol comes in a one-size-fits-all design—flexible enough to fit comfortably, whether your head is small or large. For best results, simply position the sensors so they sit gently on both sides of your forehead’s center.
