The Muse S (now sold as the Muse S Athena) is a brain-sensing headband built for two different jobs at once: real-time EEG feedback during meditation, and overnight sleep tracking once you fall asleep wearing it. This review is for people who’ve tried meditation apps that just play a timer and want actual biofeedback on whether they’re calming down, and who are willing to wear a headband to bed for it.
What it actually measures
Muse uses EEG sensors across the forehead and behind the ears to read real brainwave activity, paired with an accelerometer and gyroscope for body movement and heart/breathing rate sensors. During a guided session, the Muse app translates your brain state into real-time audio feedback — calm weather sounds when your mind settles, and correspondingly “stormier” sounds when your mind wanders — so you get a live signal instead of guessing whether the meditation is “working.” Overnight, the same sensors and the “Digital Sleeping Pills” feature (responsive audio that adapts as you drift off) feed into a morning sleep score covering sleep stages and time in each.
Price and the subscription reality
The Muse S Athena runs around $475 for the device alone, or around $540 bundled with a year of Muse Premium — check the current price before buying, since Muse runs promotions regularly. After the first year, Premium renews at roughly $45/year. That subscription is not optional if you want the full feature set: sleep optimization tools, the larger library of guided sessions, and the AI-driven “Enso” coaching are gated behind Premium, while a smaller set of core meditation and basic tracking features stays free. Buyers coming from a cheaper meditation app should budget for the subscription as a real ongoing cost, not a nice-to-have.
Honest drawbacks
Comfort and fit are the most common complaints — the headband’s fabric contact points can wear or peel within four to six months of regular use, and users with certain head shapes report sensor contact dropping out mid-session, which the app flags as a connectivity issue rather than a meditation-progress issue. Getting a clean signal at bedtime specifically (headband still positioned correctly after you’ve settled in) can take a few minutes of adjustment per session, which undercuts the “just put it on and sleep” pitch for anyone impatient with troubleshooting. And at several hundred dollars all-in for year one, it’s a serious investment compared to a low-cost meditation app, so it only pays off if you’ll actually use the biofeedback loop regularly rather than a handful of times.
How it compares
| Muse S Athena | Oura Ring 4 (sleep tracking) | Apollo Neuro (stress/calm) | |
|---|---|---|---|
| Price | Around $475 device, ~$45/yr after year one — check current price | Around $350+ device, ~$6/mo after year one — check current price | Around $300, no subscription — check current price |
| Core job | Real-time EEG meditation feedback + sleep score | Sleep stage/readiness/recovery tracking | Passive vibration-based nervous-system calming |
| Worn how | Headband, day (meditation) or night (sleep) | Ring, 24/7 | Wristband or clip, worn as needed |
| Best for | People who want live brain-state feedback during practice | People who want the most refined sleep-stage data | People who want passive calming without active meditation |
Who should buy it
People who’ve stalled out on meditation because they had no real signal that it was working, and who are disciplined enough to wear a headband both for daytime sessions and overnight. If your main goal is just accurate sleep-stage data without the meditation layer, a ring like the Oura Ring 4 tracks sleep with less friction and no headband to position correctly each night. If you want stress relief without actively meditating at all, that’s a different product category — a passive wearable like Apollo Neuro fits that use case better.
Frequently asked questions
Do I need the Premium subscription to use Muse S?
A basic set of meditation and tracking features works without it, but sleep optimization, the larger guided-session library, and AI coaching are gated behind Premium, which renews around $45/year after the included first year.
Is Muse S accurate for sleep tracking, or is it really a meditation tool first?
It’s built as a meditation-first device that added sleep tracking; most negative feedback specifically targets sleep-mode accuracy and overnight comfort rather than its real-time meditation feedback, which is the feature it was originally designed around.
Is it comfortable to sleep in?
Comfort is the most-cited drawback — some users adapt fine, but headband fabric wearing out within months and fit issues for certain head shapes are common enough complaints to take seriously before committing to nightly use.
What’s the difference between Muse S and the cheaper Muse 2?
The Muse 2 (around $250 — check current price) does real-time meditation feedback and focus/stress tracking but has no sleep-tracking mode — it’s built for daytime session use only, while the S Athena adds the overnight sleep-score feature.
