All-night headband, comfortable
The first headband to pair EEG with fNIRS (brain blood-oxygenation), used for guided meditation, neurofeedback and EEG-based sleep tracking. It is a wellness device with no FDA clearance, but it is unusually open to raw brain data for researchers and developers.
What it measures
Brainwave activity via EEG sensors plus fNIRS brain blood-oxygenation, heart rate (PPG), movement/posture (accelerometer/gyroscope), and EEG-based sleep staging with audio "Deep Sleep Boost" and Smart Wakeup.
Regulatory status
Wellness device — no FDA clearance. Marketed for mental fitness, meditation and sleep optimization, not diagnosis.
Validation & accuracy
EEG is a genuine biosignal widely used in research, and Muse is popular in academic studies; the consumer sleep/cognition claims are vendor-reported, not clinically validated for diagnosis.
Data control & export
Raw data: restricted — the app shows insights and the free app works out of the box, but advanced sleep/cognition features sit behind Premium; raw EEG is accessible to developers/researchers via the Muse SDK and community tools rather than a one-click export. API: restricted (SDK / research partner program).
Wearability & battery
A soft, lightweight fabric headband designed for all-night wear, with multi-hour battery; more comfortable than rigid EEG rigs but still a headband.
Cost & access
One-time ~$474.99. Free app works out of the box; optional Muse Premium subscription (Smart Wakeup, AI coach, cognitive metrics, external audio).
Who it serves
Meditators, sleep optimizers, and quantified-self/research users who want EEG-grade brain data.
Who is left out or burdened
Headband form factor; advanced features behind Premium; no cleared clinical output.
✓ Strengths
- First headband to combine EEG + fNIRS brain sensing
- EEG-based sleep staging with Deep Sleep Boost and Smart Wakeup
- Raw EEG accessible to researchers via the Muse SDK
- Free app works out of the box (no mandatory subscription)
✕ Weaknesses
- Wellness-only — no FDA clearance
- Advanced sleep/cognition features behind Premium
- Headband form factor; ~$475 price
- No one-click first-party raw-data export
30
Why this clinical score. A real EEG/fNIRS biosignal, but wellness-only with no cleared clinical output keeps it low on the clinical axis.
56
Why this empowerment score. Unusually open for a consumer device — researchers can access raw EEG via the SDK — but Premium gating of depth and no simple first-party export hold empowerment mid-range.
56
Why this everyday score. Comfortable enough for all-night wear with useful sleep/meditation tooling, though it is still a single-purpose headband.

Reviews & coverage
Reviewers like the softer headband form for overnight EEG sleep tracking plus daytime meditation feedback. The caveats are comfort during sleep, a premium price and the inherent limits of consumer EEG.
