How Easleep works
Three technologies working together while you sleep
Easleep (Powered by BrainCo) isn’t a sleep mask or a white noise machine. It combines three clinically-inspired technologies in a single lightweight headband.

EEG brainwave tracking
Dry sensors in the headband read the electrical signals your neurons produce — hundreds of times per second. The device maps these to your current brainwave state: awake, drowsy, light sleep or deep sleep.

Cranial electrotherapy stimulation
CES delivers micro-current pulses — weaker than a 9V battery — to your scalp. These promote the natural release of serotonin, dopamine and melatonin, reducing anxiety and guiding your brain toward sleep without drugs.

Adaptive brainwave audio
The companion app plays sleep-enhancing audio that shifts in real time based on your EEG data — binaural beats, pink noise, white noise and adaptive brainwave music that follows your mind into rest.
The companion app
Your personal sleep data, every morning
Track your sleep cycles, observe brainwave readings, and see objective statistics on your recovery every morning when you wake up. No subscription or hidden fees required.

Sleep programs
Eight sleep modes for every situation
Every mode adapts to your live EEG data — no two sessions are identical because no two nights are the same.

Frequently asked questions
Everything you need to know
How long before I notice a difference in my sleep?
Most users notice a difference in how quickly they fall asleep within the first 3–7 nights. Significant improvement in sleep quality and depth typically becomes measurable in the app data after 2–4 weeks of consistent use. Like any habit-forming technology, results improve the longer you use it.
Does it work if I have thick or long hair?
The four EEG sensors are positioned on the forehead (FP1, FP2, AF7, AF8) — not the scalp — so hair thickness does not affect the reading quality. Most hair types and lengths are compatible without adjustment.
Will it disturb my partner at night?
The headband operates completely silently. Sleep audio is delivered through your own earphones (not included) — so only you can hear it. The CES stimulation produces no sound or visible light. Your partner won’t know you’re using it.
Is my brain data stored or shared?
All raw EEG brainwave data is processed locally on your smartphone — it is never transmitted to Neuro AI servers, BrainCo servers, or any third party. The sleep report data (scores, cycle durations) is stored only on your device unless you choose to export it. Your brain data is yours.
Does the app require a subscription?
No subscription is required. Full access to all sleep modes, soundscapes, EEG sleep reports and recovery programs is included with your Easleep device purchase. There are no ongoing fees.
Are there any side effects?
Some users may experience mild and temporary effects such as: slight tingling sensation, headache, dizziness, or skin irritation. These effects are usually temporary. If discomfort persists, discontinue use and seek medical advice.
Can children use this device?
This device is intended for adult use only unless specifically advised by a healthcare professional.
Is this a medical device?
No. This product is a wellness and lifestyle device, not a certified medical device.
Does CES hypnosis operate all night?
No. For the first time of use, the device takes 15 minutes as the default duration of CES hypnosis. If you need to customize the duration of CES hypnosis, you can open the duration setting of “Scheme” in the app to adjust the set duration of CES hypnosis.
Is it normal to feel inconsistent between the left and right during CES hypnosis?
This is normal. This feeling occurs because the two sides of the forehead have different sensitivities and correspondingly different feelings for current stimulation. It will not affect the effect of equipment use.
After wearing, there is a red mark on the electrode position. Is it normal? How soon will it disappear?
It is normal that there will be a red mark on the electrode position after wearing. Please don’t worry. The red mark will disappear in about 15 minutes.
Can the electrode position be adjusted during CES hypnosis?
The electrode position can be adjusted appropriately until the gel electrode fully contacts the skin.
When should it be used and how long will it be effective?
Use it 1-2 hours before going to bed at night. It is recommended for the first time of use that you use it for 15 minutes. In addition, it is recommended that you use CES hypnosis within 90 minutes a day, and for every single use, the time should not exceed 60 minutes.
Under what circumstances can CES hypnosis be used?
It is suggested that you use this product in a comfortable and relaxed environment/state. It is recommended to keep the time period of using the product relatively consistent, which can result a better treatment effect. If you are driving, or need to stay excited or focused, you are not advised to turn on CES hypnosis.
Easleep Brain-Machine
I’ve only been using Easleep for a short time, but I’m already noticing a more relaxing bedtime routine. Great product and great customer support
I’ve been using Easleep for a couple of weeks and I’ve noticed I’m falling asleep more easily. The device is comfortable to wear and the app is very easy to use. Looking forward to seeing my long-term sleep trends.
“Honestly didn’t expect much, but the Easleep has helped me switch off faster at night and wake up feeling more refreshed. Easy to use and comfortable to wear.”
Been using the Easleep for a couple of weeks and it’s made a real difference. Falling asleep quicker and not waking up as much during the night. Easy to use and actually feels like it’s working with your body, not against it. Worth it if sleep’s been a struggle.
