Endel: The Science of Endel

The Science of Endel

Sound has a direct impact on our physical and mental wellbeing. It has the power to affect our sleep, mood, concentration levels, blood pressure, and more.

Endel takes everything we know about sound and combines it with cutting-edge technology. The result is real-time, personalized soundscapes, designed to help you relax, focus, and sleep.

Endel is informed by science, created with science, and backed by science.

Our patented technology



Our patented core technology, Endel Pacific, adapts in real-time to personal inputs like location, weather, and heart rate.

Circadian Rhythms

Circadian Rhythms

Your biological clock is in tune with nature’s organic rhythms and cycles. Endel complements these to improve how you feel – night and day.

Pentatonic Scale

Pentatonic Scale

Endel uses pentatonic scale and pure intonation to create simple sounds that are both pleasant and physiologically natural.

Sound Masking

Sound Masking

Endel soundscapes use specially-tuned noises to make distracting sounds and harsh interruptions less audible.

We’ve collaborated with leading sleep scientists to create soundscapes that naturally facilitate restful slumber.

Neuroscience backed

Neuroscience backed

Brainwave studies show that Endel provides the fastest, most consistent focus vs playlists on streaming platforms.

Endel stays in tune with you

Endel soundscapes react in real-time to your natural rhythm, physical state, and environment.

Natural light & Weather

Endel compensates for the lack (or excess) of light outside by adapting the soundscape’s intensity. It also reacts to the outdoor temperature.

Heart rate

Endel adjusts to your real-time heart rate using data from the Apple Health or Google Fit app and comparing it with your normal resting heart rate.


Endel alters sound intensity according to the number of steps taken per minute during your walking session.

Endel Pacific: Our patented core technology

Endel Pacific is the technology that powers all of our products. It takes inputs like location, environment, and heart rate, to create the optimal personalized soundscape. This happens on the fly, reacts to changes, and allows Endel to sync a user state with the circadian rhythm.*

decrease in stress with regular use**
Longer, more consistent focus; maintained 95% of listening time**

Proven for consistent focus

Scientifically engineered to keep you focused

According to a study by pioneering data and technology company, Arctop, Endel’s personalized soundscapes provide faster, more consistent focus than playlists on top streaming platforms. It’s shown to give you a 7x increase in focus, maintained 95% of listening time. Read the full study on biorXiv.
