Frequently Asked Questions

Q: How does the CES cranial electrotherapy stimulation device work?

A: The CES device delivers gentle, low-amplitude micro-current pulses (within the 0–15 Hz range) through conductive ear clips placed on the earlobes. These micro-currents are designed to mimic the brain's naturally occurring electrical signals, encouraging a calm and relaxed mental state that can support a smoother transition into sleep.

Q: How long does the battery last, and how do I charge it?

A: The built-in 600mAh battery takes approximately 4–5 hours to fully charge via the included charging cable and universal adapter. With one hour of use per day, a single full charge supports up to 10 days of sessions — making it excellent for travel or everyday home use.

Q: Is this device safe for everyone to use?

A: This cranial electrotherapy stimulation device is intended for extraoral use by adults. It should not be used by individuals with implanted electronic devices (e.g., pacemakers), or alongside high-frequency surgical, short-wave, or microwave therapy equipment. We strongly recommend consulting your healthcare provider before use, especially if you have any pre-existing health conditions.

Q: What does the auto-setting mode do?

A: The AUTO work mode automatically manages the session timing — typically running for around 5 to 30 minutes — so you don't have to manually monitor or stop the device. Simply clip on the ear clips, power it on, and let the device do the rest as you relax.
