A precision bedside instrument for the deliberate sleeper. Engineered to shape light and sound across your night. Not a gadget. A tool for discipline.
Learn MoreThreshold learns your circadian rhythm. Its spectral array generates precise wavelengths across the night—cool light during deep sleep, warm light as morning approaches. No harsh transitions. Just inevitable dawn.
Acoustic masking refined to a science. Threshold generates sculpted noise—filtered white noise, pink noise, brown noise—chosen by the hour. Disturbances are dampened before they reach consciousness.
Threshold contains no algorithms you do not understand. No machine learning. No wireless dependencies. Every parameter is visible, adjustable, deliberate.
16 million color combinations. Precision to ±5nm wavelength. Temperature sensor maintains output across ambient conditions.
Dual 2-inch drivers. Real-time DSP. Frequency response 20Hz–20kHz with custom filtering for each noise profile.
No app. No wireless. Physical, tactile, immediate. Your sleep pattern lives in this device, not in the cloud.
We live in an age of productivity theater. Every moment must yield output. Sleep is treated as lost time. But sleep is where the work happens. Where your nervous system repairs itself. Where memory consolidates. Where you become yourself again.
Threshold is built for people who understand this. Not for sleep optimization—a contradiction. But for sleep respect. For the person who treats rest as a discipline. Who knows that the quality of your sleep determines the quality of your waking hours.
Threshold is available by inquiry. We make a limited number each year.
