The direct answer: these three products take genuinely different approaches to the same broad goal. Muse S Gen 2 ($399.99) reads your actual brainwaves via EEG and turns them into real-time audio feedback during meditation or sleep. Apollo Neuro ($290) delivers pre-set vibration patterns to your wrist or ankle designed around specific goals like focus or sleep. Sensate 2 ($299) uses infrasonic vibration against your sternum, aimed at the vagus nerve via bone conduction. None of the three work the same way, despite landing in similar marketing territory.
At a Glance
- Best for real biofeedback data: Muse S Gen 2 ($399.99) — actual EEG brainwave sensing, not just a vibration pattern.
- Best for discreet, wearable use: Apollo Neuro ($290) — worn on the wrist or ankle throughout the day.
- Best for a dedicated short session: Sensate 2 ($299) — a focused 10-minute lie-down session rather than all-day wear.
Muse S Gen 2: Actual EEG, Not Just Vibration
Muse S Gen 2 costs $399.99 and is a genuinely different category of device from the other two: a soft fabric headband with four primary EEG channels plus two auxiliary sensors, using silver-threaded contacts to detect real brain activity at a 256Hz sampling rate. It also layers in photoplethysmography for heart rate, an accelerometer, and a gyroscope for head-position tracking, and translates that live brain data into responsive audio feedback — calmer brainwave patterns produce calmer soundscapes in the app, functioning as real-time neurofeedback.
Battery life runs about 10 hours per charge, with a roughly three-hour full recharge. Core meditation and sleep-tracking features work without a subscription; an optional premium tier around $13/month or $100/year unlocks additional guided content on top of the free core experience.
Apollo Neuro: Curated Vibration Patterns, Worn All Day
Apollo Neuro costs $290 and works through touch — a wrist- or ankle-worn device delivers specific vibration patterns (“vibes”) selected in its companion app for goals like focus, relaxation, sleep, social ease, energy, or recovery, each with its own curated intensity and duration. A “focus” session uses noticeably stronger vibration than the gentler “fall asleep” pattern, for instance.
It works without any subscription for manual vibe selection; an optional SmartVibes membership adds automated, responsive adjustments for sleep and morning routines rather than requiring you to pick a vibe manually every time.
Sensate 2: A Dedicated Session, Not All-Day Wear
Sensate 2 costs $299 and takes a third approach entirely: a smooth device placed on your sternum (typically worn on a necklace during a session) that emits infrasonic vibrations designed to reach the vagus nerve via bone conduction, paired with composed soundscapes in its app. It’s built around short, dedicated sessions — the company markets “calm in 10 minutes” — rather than continuous all-day wear.
No subscription is required to use the core device — an optional Sensate Plus tier exists for additional content. The company cites internal and pilot study figures including a 48% stress-level decrease over 28 days of use and roughly 60 extra minutes of sleep per night in a sleep-focused pilot; treat company-cited study figures as claims to verify independently rather than settled science.

So Which One Should You Actually Buy?
Buy Muse S Gen 2 if you want real biofeedback data — actual brain activity, not just a pre-set pattern — and are willing to wear a headband during dedicated sessions or overnight. Buy Apollo Neuro if you want something you can wear invisibly under a sleeve throughout a normal workday, using vibration cues rather than any biosensing. Buy Sensate 2 if a short, dedicated wind-down ritual fits your routine better than continuous wear, and you’re comfortable with a device you hold or wear briefly rather than all day.
How We Compared
We did not test any of these three devices ourselves for this comparison. Mechanism details and pricing were verified against each brand’s own current product pages, and we were deliberate about distinguishing Muse’s actual EEG sensing from Apollo Neuro’s and Sensate’s vibration-based approaches rather than treating all three as functionally identical “calm wearables.” More on our process is on our editorial standards page. Prices are approximate, current as of publication, and change frequently — confirm the latest price with the retailer before buying.
FAQ
Which of these devices actually reads brain activity?
Only Muse S Gen 2, using four EEG channels plus auxiliary sensors to detect real brainwave activity. Apollo Neuro and Sensate 2 both work through vibration patterns rather than reading any brain or nerve signal directly.
Are Apollo Neuro or Sensate 2 FDA-cleared for anxiety treatment?
No. Both are consumer wellness products, not FDA-cleared medical devices for treating anxiety or any diagnosed condition. Talk to a mental health professional about ongoing anxiety rather than relying on either device as treatment.
Can I wear these devices all day, or are they session-based?
Apollo Neuro is built for continuous all-day wear on the wrist or ankle. Muse S Gen 2 is used during dedicated meditation sessions or overnight sleep tracking. Sensate 2 is designed around short, dedicated sessions of around 10 minutes rather than continuous wear.
Do any of these require an ongoing subscription?
No core function on any of the three requires a subscription. All three offer an optional paid tier for additional content or automation, but the base device works without ongoing payment.
