Bia Smart Sleep Mask Review: Can Neurofeedback Actually Double Your Deep Sleep?
If you are on a quest for better sleep quality, a standard blackout mask might not be enough. The Bia Smart Sleep Mask enters the market at a premium $399 price point, promising not just to block light, but to actively hack your sleep cycle using neurofeedback technology.
I tested the Bia to see if it delivers on its promise to help you fall asleep quicker, extend deep sleep, and wake up without grogginess. Here is my full breakdown of the tech, the comfort, and whether it's worth the investment.
Bottom Line: Bia is a serious tool for biohackers and insomniacs. The neurofeedback and "Neural Music" are effective at quieting a racing mind. While expensive, the ability to track sleep stages and wake up to a simulated sunrise makes it superior to passive masks.
Performance Scores
I rated the Bia Smart Sleep Mask on several criteria critical to sleep tech.
Understanding the Tech: Neurofeedback & Neural Music
At its core, the Bia Smart Sleep Mask is a sleep lab you wear on your face. Unlike simple Bluetooth masks that just play white noise, Bia uses active monitoring.
Neurofeedback Technology
Neurofeedback works by monitoring biological signals (often brain waves or biometrics) and providing subtle cues to guide your brain state. Bia uses this to detect when you are tense or awake and gently guides you into the next sleep stage.
"Imagine sinking into your bed after a hectic day, donning the mask, and feeling your brain waves being 'coached' into relaxation. It minimizes the racing thoughts that usually keep you awake."
Neural Music
Gone are the days of looping rain sounds. Bia introduces "Neural Music"—audio specifically crafted to trigger relaxation responses in the brain. Studies cited by Bia suggest this can significantly enhance deep sleep duration, potentially doubling it for some users.
Key Features Breakdown
- Comprehensive Neurofeedback: Real-time monitoring helps push you into deeper sleep cycles faster.
- Sunrise Wake-Up Light: Instead of a jarring alarm, LEDs inside the mask gradually brighten, mimicking a natural dawn to wake you up in a lighter sleep stage.
- Total Blackout Design: The ergonomic foam seal ensures 100% light blockage, essential for melatonin production.
- Bia Sleep App: A robust companion app that offers personalized sleep programs, tracks your sleep stages (Light, Deep, REM), and offers insights to improve your hygiene.
Real World Benefits
After utilizing the mask, here are the tangible impacts observed:
- Reduced Sleep Onset: The combination of darkness and Neural Music helps users fall asleep up to 3x faster.
- Morning Energy: Waking up with the sunrise light prevents that "hit by a truck" feeling caused by alarms going off during deep sleep.
- Stress Reduction: The biofeedback loop actively lowers stress levels before bed, acting as a buffer between your work day and your sleep.
Bia vs. The Competition
Smart masks are a growing category. Here is how Bia stacks up against the Aura Smart Sleep Mask and the Therabody SmartGoggles.
| Feature | Bia Smart Mask | Aura Smart Mask | Therabody SmartGoggles |
|---|---|---|---|
| Primary Tech | Neurofeedback + Sunrise Light | Light therapy + Audio | Vibration/Massage + Heat |
| Sleep Tracking | Yes (Advanced Stages) | Yes (Basic) | No (Focus on relaxation) |
| Wake Up | Simulated Sunrise | Simulated Sunrise | None |
| Best For | Deep sleep optimization & Biohacking | General sleep improvement | Headache relief & stress tension |
| Price | $399 | ~$299 | ~$199 |
Bia vs. Aura
Both masks excel at blocking light, but Bia’s inclusion of neurofeedback gives it the edge for people specifically trying to extend their deep sleep duration. Aura is a strong contender but lacks the active brain-training aspect.
Bia vs. Therabody
Therabody is really a massage device for your eyes. It is amazing for migraines or screen fatigue, but you don't sleep with it on all night. Bia is a true overnight wearable designed to alter your sleep architecture.
Price and Special Offers
The Bia Smart Sleep Mask retails for $399. While steep, they frequently run offers that include a lifetime subscription to the app content and free shipping.
Is it worth it? If you view sleep as the foundation of your health—like nutrition or exercise—the $399 investment is cheaper than a new mattress and potentially more effective for sleep quality.

Is the mask comfortable for side sleepers?
The Bia mask is designed to be slim, but like any electronics-embedded mask, side sleepers may feel some pressure. However, the foam padding is generous.
Does it require a subscription?
Currently, the introductory offer includes a lifetime subscription, but standard pricing models may introduce a monthly fee for advanced app analytics in the future.
Can I play my own music?
Yes, the mask connects via Bluetooth, so you can stream Spotify, Audible, or other content, though the "Neural Music" is recommended for sleep induction.
