Read our full Endel review

Quick Verdict

Endel is impressive technology: real-time adaptive soundscapes that respond to your heart rate and time of day. But the full version is a paid subscription, $19.99 a month or $119.99 a year in the US, so it's a commitment. NSDR is free, web-based, and uniquely pairs focus music with NSDR recovery protocols. For most people who just need to focus, NSDR delivers without the subscription.

NSDR is best for

People who want free focus music you can start in the browser with binaural beats and NSDR recovery sessions, with no downloads or accounts needed

Endel is best for

Users who want personalized, adaptive soundscapes that respond to biometrics (heart rate, movement) across the Apple ecosystem

Try free focus music for 60 seconds

This is not Endel. It is NSDR.co's free Focus Mode, so you can hear the free option before you decide. Pick Deep Work or Study and press play. It stops after 60 seconds.

Deep Work

Lofi, with a beat layer that starts near 10 Hz and climbs towards 18 Hz.

60 seconds

Free to use, always a free plan.

Open the full Focus Mode

Use headphones if you can. The beat layer is binaural, so each ear needs its own channel. A second pulse is built into the music, so it still works on speakers.

Detailed Analysis

How They Stack Up

Adaptive AI vs Binaural Beats

Endel and NSDR represent fundamentally different philosophies. Endel adapts to you in real-time; NSDR gives you proven tools to control your own focus.

No algorithms deciding what you need: you choose your focus track and get to work

Endel

Proprietary AI engine (Endel Pacific) generates never-repeating soundscapes on-device
Adapts to time of day, weather, heart rate, and movement in real-time
Cites a 2022 peer-reviewed study it co-funded, which found higher focus than with silence while people worked
