In the highly industrialized society today, we are surrounded by various types of sound, which are not necessarily comfortable. More and more people are complaining about sounds they tolerate in their daily lives that interfere with their sleep or concentration. Recent studies reveal that one in five people today are HSP (Highly Sensitive Person), some of whom suffer from acoustic hyperesthesia that makes them too sensitive to everyday sounds to tolerate.
Therefore, we created this product. Whenever and wherever you are, pick up EP-S433, then you will feel the comfort of "sound insulation" and spend your time with peace of mind. We hope that the experience of "closing your ears" will help you stay in tranquility.
