About the Relaxonic Cover Ultra-High Frequency Eye Mask
The Relaxonic Cover offers deep rest in a short space of time through an innovative approach that combines hypersonics, ultra-high frequency sound waves felt by the skin rather than the ears, with a heat function. This eye mask aims to maximize refreshment in a limited amount of time with 15 different sounds, including hypersonics, which are inaudible to the human ear and exceed the high-resolution sound range, and a heat function that warms the eye area. By selecting your preferred healing sound through the smartphone app and spending 5 to 20 minutes with the mask, you can enjoy a short, comfortable rest even in the midst of a busy life.
