01 / RHYTHM
Built around rhythm
A custom rectangular pulse waveform delivers gentle, steady, and controlled stimulation.
How Sleep X1 Works
A gentler approach to cranial electrical stimulation
CES, or cranial electrotherapy stimulation, is a non-invasive approach that delivers low-intensity electrical signals through electrodes placed on the head. TRANOO Sleep X1 uses gentle, adjustable stimulation designed to support a calmer transition into rest, with an experience intended to feel subtle and comfortable rather than intense.

02 / SLEEP
Why it relates to sleep
As the body prepares for sleep, brain activity naturally shifts into patterns associated with rest. Low-intensity electrical stimulation is designed to support this natural transition.
03 / COMFORT
Gentle, not aggressive
The experience is intended to feel subtle and adjustable, supporting comfort rather than forcing a response.
Principle behind Sleep X1
From Signal to Stimulation
A simple look at how low-intensity electrical stimulation is delivered through TRANOO Sleep X1.
Step 01
Controlled Signal
The control module generates a preset, low-intensity electrical signal designed for a controlled 15-minute session.
Step 02
Stable Skin Contact
Integrated electrodes deliver the signal through designated contact points, while the mask helps maintain stable and comfortable contact with the skin.
Step 03
Neural Interaction
The resulting electrical field may interact with neural activity involved in the transition from alertness to a calmer resting state.
Technical Note
The experience may vary depending on electrode contact, individual impedance, and the selected stimulation level. TRANOO provides adjustable intensity levels and a fixed session duration to support a controlled experience.

Science Over Time
Over a Century of Exploration
Research into transcranial electrical stimulation spans more than 100 years. From early experiments to modern brain-imaging and measurement studies, researchers have continued to explore how low-intensity electrical signals interact with neural activity.
TRANOO draws on principles from this long-studied field and brings them into a simple, adjustable 15-minute wellness routine.
Early Exploration
Researchers began examining how externally applied electrical currents interact with the head and nervous system.
Imaging & Measurement
Brain-imaging and direct measurement studies continue to investigate neural activity and electrical-field distribution.
Simple Wearable Format
A lightweight, adjustable format designed for a straightforward 15-minute wind-down routine.
Research Note
Scientific understanding continues to evolve. The research described here relates to the broader field of transcranial electrical stimulation; devices, stimulation parameters, and individual experiences may differ.
Different Ways to Wind Down
Why Microcurrent?
A closer look at how different relaxation approaches deliver sensory input—and why TRANOO uses a low-intensity electrical approach.
Sound
Music, white noise, or rhythmic audio can shape the surrounding sound environment.
Drawback
Prolonged listening, especially at higher volumes, may increase the risk of hearing damage.
Light
Changes in brightness or color can help create a calmer nighttime environment.
Drawback
Excessive nighttime light may interfere with melatonin release and natural sleep rhythms.
Heat
Warmth can create physical comfort and support a more soothing environment.
Drawback
May cause sweating and often relies on bulky products that are less convenient to carry.
TRANOO
An adjustable low-intensity electrical signal is delivered through comfortable skin contact.
Advantage
A lightweight, portable option designed to minimize discomfort and unwanted sensations during use.
