“Use it every night as part of my wind-down routine — clip it on, set the timer and that's it. I'm usually asleep before the 20 minutes is up. Very easy to use and completely comfortable to wear.”— F***a, London, Verified customer
CES SLEEP AID
The CalmWave uses CES (Cranial Electrotherapy Stimulation) technology delivered through two ear clips worn at bedtime. The LED display shows the active session timer. The timer is adjustable from 5 to 30 minutes, with automatic power-off when the session ends — so there is nothing to switch off if you fall asleep. Drug-free and non-invasive, as confirmed on the device packaging.
WIND-DOWN ROUTINE
Place the ear clips on both ears, set your preferred session length using the Mode and Power buttons, and rest. The CalmWave runs silently for the duration of the session and switches off automatically. The LED display stays visible on the bedside table while you lie down. Most users incorporate it into a consistent pre-sleep routine — same time each night, same duration.
CES TECHNOLOGY
CES (Cranial Electrotherapy Stimulation) is a category of device that delivers small, low-level electrical pulses through contact points placed near the head — in this case, via clips attached to the earlobes. The signal intensity is adjustable and the sensation during use is typically described as a mild, barely perceptible pulse. The CalmWave is not a medical device and is designed for home use as part of a sleep preparation routine.
4 CONTROLS. LED DISPLAY.
The CalmWave controller has four physical buttons — Power, Mode, Power+ and ON/OFF — to set the session length and intensity without needing to look at a screen or open an app. The LED display shows the remaining session time and battery level at a glance. The device recharges via USB and fits easily in a bedside drawer or travel bag.

I've had persistent sleep issues for years and tried everything. CES therapy was recommended as a non-medication option and this device has genuinely made a difference. I use the ear clips for 20 minutes before bed on the lowest setting — I fall asleep faster and wake less frequently during the night.
The round electrode option is useful for targeted use on the temples during the day for anxiety management. Small enough to fit in a bag and the battery life is excellent — I charge it once a week with regular use. The different modes took a few sessions to explore but the manual is clear.
Everything arrived well-packaged with a clear operating manual and all the accessories included — USB cable, ear clips, and electrode pads. Setup was straightforward and I was using it the same evening. The device is solid and well-built for its size.
I was sceptical about CES therapy initially but after four weeks of consistent evening sessions my sleep quality has measurably improved. The travel case is a thoughtful addition — I take it when I travel and it's made a real difference to sleep in unfamiliar places. Genuinely impressed.
CES stands for Cranial Electrotherapy Stimulation. The CalmWave delivers small, low-level electrical pulses through two ear clips worn at the earlobes. The intensity is adjustable via the control buttons. The sensation during use is typically a mild, barely noticeable pulse. The CalmWave is designed for home use as a pre-sleep relaxation routine — it is not a medical device and does not claim to diagnose or treat any condition.
Attach the two clips to the earlobes — one on each side. The clips sit comfortably on the earlobe and do not require any conductive gel or skin preparation. Once attached, turn the device on using the ON/OFF button, set your preferred session length using the Mode button, and adjust the intensity with Power and Power+. Place the controller on the bedside table and lie down.
The timer is adjustable from 5 to 30 minutes. The default session length is 20 minutes, after which the device switches off automatically. Most users run the full 20-minute session as part of their bedtime routine. Start at a lower intensity for the first few sessions and adjust upward as you become familiar with the sensation.
The CalmWave is designed to be worn while falling asleep. The automatic power-off function switches the device off when the session timer ends — there is nothing to switch off manually if you fall asleep during a session. The ear clips are lightweight and designed to stay in place comfortably during rest. If you find the clips uncomfortable during the night, remove them before lying down and allow the timer to run.
The CalmWave operates silently — there is no audio output. The electrical pulse through the ear clips is low-level and typically described as a mild, barely perceptible tingling at lower intensity settings. At higher settings the sensation becomes more noticeable but should not be uncomfortable. Reduce the intensity if the sensation feels too strong.
The CalmWave recharges via USB. Connect the charging cable to the device and plug into any USB power source — a wall adapter, laptop or power bank. The LED display shows the battery level during use. A full charge supports multiple sessions before recharging is needed. Store the device with the ear clips coiled to avoid cable tangling.
