α-θ Brainwave Sync for Deeper Stillness

Fall asleep faster, think clearer, and feel more centered—without pills, apps, or side effects.

What frequency is the most suitable for emotional healing and stress relief?

We recommend using 7.83Hz for emotional healing. The pure sine wave output can create a gentle and soothing atmosphere, effectively reducing daily stress and restoring inner harmony.

Is this device difficult to set up? I don't really understand electronic products.

How are sine waves and square waves used?

The sine wave is smooth and continuous. It is the most natural waveform and is very suitable for sleep, deep rest, meditation, all-day relaxation, and long-term background playback scenarios. Most users default to using the sine wave at night or choosing it in environments that require calm and stability.
The square wave is sharper and more energetic. They can convey stronger signals, so they are more suitable for concentration, refreshing, morning routines, or deep targeted training. You can consider the sine wave as your evening mode and the square wave as your daytime mode.

A SIMPLE START

Get familiar in three steps.

Check the power

Confirm your model’s power requirements. Charge a rechargeable device or connect a USB-powered model as directed. Place it on a stable, dry surface.

Check the settings

Use the screen to review the selected frequency and waveform. Set a timer if your model includes one; do not assume all models share the same controls.

Keep your routine simple

Read, journal, stretch, or meditate as you normally would. Use the display or the manual’s checks—not a promised sensation—to confirm operation.
