The short version

What it is: a brain-sensing (EEG) headband that turns your brain activity into sound while you meditate. The Muse S Athena also tracks sleep. It measures; it doesn't stimulate anything, your vagus nerve included.
Price: Muse 2 $249.99, Muse S Athena $474.99 (as of October 2026). The core feedback works without a subscription.
Best for: people who keep abandoning meditation apps, never sure they're doing it right, and data-minded 3am wakers who want brain-based sleep stages.
Skip it if: sleep data makes you more anxious, you can't sleep in a headband, or you want a device that acts on your nervous system rather than reading it.
The honest take: the sleep tracking has respectable independent support. The bigger promise, that hearing your brain makes meditation work better, isn't proven. And the return policy is tighter than "30 days" suggests.

"Am I even doing this right?"

You're eight minutes into a meditation app, eyes closed, and you realize you've spent the last four drafting a reply to your sister. You drag yourself back, feel faintly like you've failed a test nobody set, and two weeks later the app has drifted to page three of your phone.

That nagging question is the gap Muse aims at. Instead of a voice telling you to notice your thoughts, the headband notices for you and answers in sound. For a results-minded skeptic, it's an appealing pitch.

What it is and how it works

Muse is made by InteraXon, a Toronto company. Sensors on your forehead and behind your ears pick up your brain's electrical activity, and the app translates it into weather sounds: a busier mind brings louder weather, a calmer one brings quiet and the occasional bird. Both current models also track heart rate, breathing and stillness.

Muse's terms say it isn't a medical device or designed to treat anything, and we found no FDA clearance.

Which Muse should you choose?

Muse 2 ($249.99): a firm band that sits over your ears, built for daytime sessions. About 5 hours of continuous use per charge. No overnight sleep staging.
Muse S Athena ($474.99): a soft fabric band with a pod on your forehead, launched in March 2025. It adds overnight sleep stages, Deep Sleep Boost (quiet sounds timed to deep-sleep brain waves), and fNIRS, near-infrared light that estimates blood oxygen in the front of your brain for "mental endurance" training. About 10 hours of battery, so daily charging if you sleep in it.
Muse S (Gen 2): the older sleep model, gone from Muse's US store. A discounted one elsewhere lacks fNIRS.

I'd start with the Muse 2 if you want a meditation habit. The Athena makes sense only if 3am is the main problem and you can sleep comfortably in a headband.

Is this a vagus nerve device?

No. Muse doesn't send current or vibration into your body. It only listens. Muse's blog discusses the vagus nerve in the context of slow breathing, but Muse doesn't claim the headband stimulates it. For direct stimulation, see the electrical stimulation category.

It earns a place here anyway. Much of what settles a fried nervous system, like stepping out of the 3am spiral and sleeping better, comes down to practice. Muse is a practice tool with a feedback loop, plus a sleep tracker that reads your brain directly. Different tool, same goal.

What the evidence actually says

Does it measure accurately? Reasonably, yes.

Brain signals (2017): University of Victoria researchers recorded 60 people on a Muse and found the same classic brain responses seen with a 64-electrode research system. Government-funded, no InteraXon ties declared. The catch: few sensors, and sensitivity to blinks and fit.
Sleep stages (2025): University of Ottawa researchers had 56 adults spend a lab night in a Muse S alongside full polysomnography. Nine recordings (16%) were discarded for poor signal. In the other 47, Muse's automatic scoring agreed well with a blinded sleep technologist (accuracy 88 to 96% by stage). InteraXon supplied the headbands but didn't fund it. Average age was about 32.

Does the feedback beat ordinary meditation? Not clearly.

The best summary (2025): researchers at MIT, Columbia and elsewhere pooled 16 randomized trials (763 people) of consumer neurofeedback meditation; 11 used Muse. Against controls, mostly ordinary meditation apps, neurofeedback produced a small drop in distress and no improvement in mindfulness, thinking or physical health. People didn't measurably change the brain signals being fed back, and the authors raise "neurosuggestion," a placebo effect of brain tech.
A head-to-head (2021): 53 students meditated daily for a month with an app alone or app plus Muse. Both groups became less distressed and more mindful, and Muse's calm scores didn't track mindfulness.
Midlife women (results posted 2026): Mayo Clinic gave Muse S headbands to 31 women aged 45 to 65 with poor sleep. Seventeen dropped out. The 14 who finished reported better sleep quality at six months, but there was no comparison group, and women on HRT or with moderate to severe hot flashes were excluded.
Muse's own numbers: "54% less burnout" comes from a 40-person Mayo pilot with no control group. "20% better sleep quality" comes from a 2021 study InteraXon collaborated on, with no published results we could find. We found no source for "55% faster sleep onset."

So: decent measurement, unproven benefit over plain meditation. More on reading studies like these in The Science.

What owners commonly report

On Trustpilot, Muse has 4.0 out of 5 from about 2,390 reviews: 60% five-star, 14% one-star (as of October 2026). The app has 4.3 stars from about 1,500 App Store ratings.

Happy owners say the feedback helps them catch a wandering mind and stick with a daily habit. Complaints cluster around the battery not lasting the night, Bluetooth drops, sleep sessions that don't save, and a band that must be snug to read well, which some find uncomfortable in bed. Worn fabric pads, slow support and drawn-out refunds come up too, and a few recent reviewers say "new" headbands arrived used.

Price, returns, subscriptions and HSA/FSA (as of October 2026)

Muse 2: $249.99, or $309 with a year of Premium.
Muse S Athena: $474.99, or $539 with a year of Premium.
Free: neurofeedback meditation, core meditations, and on Athena, sleep tracking and Deep Sleep Boost.
Premium: guided sessions, Smart Wakeup, an AI coach and extra scores. Muse's Premium page says $12.99 a month or $49.99 a year, but Muse's own store and the App Store list annual plans at $94.99 to $109.99. It auto-renews, so check the renewal price.
Returns: the "30-day money-back guarantee" covers direct orders only, used no more than 20 days from delivery and received back within 30. You need a return authorization and the original packaging, and all shipping costs are yours.
Warranty: one year; a replacement may be refurbished.
HSA/FSA: through Truemed, US only, if a provider reviews your health survey and issues a letter of medical necessity. Not guaranteed, and the IRS warned in 2024 that such letters don't automatically make wellness purchases eligible. Ask your plan.

In practice, that's a 20-day trial with your own postage. I'd wear it daily from delivery and decide by day 18.

How it compares

Apollo Neuro ($448 with a year of membership, then $99 a year) and Sensate ($299, 90-day guarantee): these act on your body with vibration instead of measuring it. They do some of the calming for you; Muse teaches you to do it. More in the vibration and sound category.
HeartMath Inner Balance Coherence Plus ($249): an ear-clip sensor that gives live feedback on your heart rhythm (HRV). Lifetime app, 60-day money-back guarantee, and HSA/FSA eligible per HeartMath. If breathing and HRV interest you most, it's the simpler buy.
A plain meditation app: Insight Timer's free library is enormous. Apps like it were the usual comparison in the meta-analysis above, and the gap was small.

Who should skip it

Sleep tracking makes you anxious. Sleep researchers call the chase for perfect sleep data orthosomnia. If an HRV dip already ruins your morning, brain-wave sleep scores won't help.
You want a vagus nerve device. This isn't one.
You can't sleep in a headband. The Athena's pod sits on your forehead and the band must be snug. Stomach sleepers, and anyone who gets headaches or skin trouble from tight bands, should think twice.
You've had seizures or react to flashing lights. Muse's terms flag rare reactions to flashing phone screens and advise checking with your doctor.
You want treatment for insomnia, anxiety or depression. Muse says it isn't designed for that. If 3am brings a pounding heart, night sweats or low mood, talk to your doctor, including about HRT.

Sit or lie comfortably and breathe normally. Silently count each out-breath from one to ten, then start again. When you lose count, or catch yourself at fourteen, notice where your mind went and go back to one. Let each out-breath run a little longer than the in-breath. Five minutes is plenty.

Losing count and coming back is the exact skill Muse rewards with birdsong. It isn't failing; it's the rep. If counting gives you enough feedback, you may not need $250 of it. If you honestly can't tell when you've drifted, that's the case for the headband. More no-cost options are in the Analogs.

FAQ

Is Muse worth it?

If knowing when your mind wanders is what finally makes meditation stick, it can be. Just know the research shows only a small edge over meditating with an ordinary app, possibly partly placebo.

Muse 2 vs Muse S: which should I buy?

The Muse 2 ($249.99) for daytime meditation. The Muse S Athena ($474.99) if you also want overnight sleep stages and can sleep in a soft headband (as of October 2026).

Does Muse need a subscription?

No. Feedback, core meditations and Athena's sleep tracking are free. Premium adds guided content and extras for $49.99 to $109.99 a year depending on where you buy it, so check first.

Is Muse sleep tracking accurate?

In an independent one-night lab study, it matched a sleep technologist well, though 16% of recordings were unusable. Good for a consumer device, but it can't diagnose anything.

The bottom line

Muse is an honest piece of kit wrapped in slightly bigger promises. It reads your brain reasonably well, its sleep tracking has independent support, and for people who need proof they're doing something, the feedback can make a habit stick. It hasn't shown that hearing your brain beats plain practice. With a 20-day return clock and murky Premium pricing, I'd buy it only with a clear goal and a calendar reminder.
