Comfort Strap
The wrap-around headband distributes weight evenly and blocks peripheral light, holding the face module securely against any head shape.
Human State Optimization
Float Above Stress.
STILL is a multisensory immersive eye mask. Spatial audio, precision facial haptics, blackout immersion, and guided rhythm work in concert to shift you from high-pressure mode into deep recovery — in minutes.
The first piece
We don't treat disease. We optimize human state.
STILL is the first piece of Mental Infrastructure — a hardware ritual for state recovery.
The experience
Not an eye mask. A personal state-switching system.
STILL pulls attention from the outside world back into the body — through sound, rhythm, and synchronized haptics — creating the sensory conditions for stillness, focus, or pre-sleep recovery.
The form
Precision-crafted for the human face.
Contoured geometry. Medical-grade fabric. A shape engineered for total blackout immersion — not pressure.
The wrap
Full coverage. Zero distraction.
The wrap-around strap blocks peripheral light and anchors the eye module in place. Velcro closure adjusts to any head shape.
Not another gadget.
A sensory architecture.
Made for real life
Engineered to Detach.
Lift the face module off in one motion — check your phone, take a call, or step back into the room while STILL's sound and haptics keep running. Total blackout when you want it; eyes open when you don't.
Eye Module
The sensory core — five haptic transducers, six spatial audio speakers, and blackout-grade cushioning. Lift it away and the open eye-ports let you see again, without taking STILL off.
Control Unit
The brain of STILL. Bluetooth 5.3, onboard processing, rechargeable battery. Mounts magnetically to the forehead bridge.
Every angle
See it from every side.

The framework
Three Core Technologies
Human State Optimization as a unified technology framework — fusing multisensory immersion, low-frequency rhythm, and adaptive algorithms.
01
Multisensory Neural Fusion
多感官神經融合技術
3D audio, facial haptics, blackout immersion, guided voice, and energy modules act in concert — creating a deeply immersive, high-presence, high-safety experience.
02
Precision Vibro-Entraining
精準低頻共振技術
Low-frequency rhythmic stimulation at high-perception points — third eye, temples, eye area — pulls attention back to the body and reduces mental drift.
03
BioAdaptive Intelligence
AI 自適應人體狀態引擎
Version 2 integrates IMU, heart rate, posture, and acoustic compensation — adapting vibration intensity, frequency, and soundfield in real time to your state.

Frequently asked
What is Chill STILL?
Chill STILL is the first piece of Mental Infrastructure — a multisensory immersive eye mask that combines 3D spatial audio, precision facial haptics, and guided rhythm to shift the wearer from high-pressure mode into deep recovery in minutes. It is built on Chill Company's Human State Optimization methodology and ships with a companion app.
How much does Chill STILL cost?
There are two tiers: STILL is US$549 and STILL Pro is US$639. STILL includes 3D spatial audio (6 speakers), one precision haptic motor, the guided experience, and the companion app. STILL Pro adds three precision haptic motors plus priority software updates and creator-platform access.
What is the difference between STILL and STILL Pro?
STILL Pro includes everything in STILL plus three precision haptic motors (versus one), priority software updates, and priority access to the creator platform. Both tiers share the same 3D spatial audio, guided experience, and companion app.
Is Chill STILL a meditation or sleep device?
Not exactly. STILL is Personal Recovery Technology — it actively moves your nervous system into recovery, rather than just playing sounds while you drift off. It is maintenance for the system your whole day runs on, so you return sharper — not a way to escape the world.
