✅ [Caution] This product may not be effective depending on the individual. In that case, please contact our support service. ✅ [2023 improved version] Major update! The earpieces have been revised for people with small ears, the case has been changed to a silent plastic case, and new colors have been added. ✅ [Earplugs for people with hyperacusis/weather sensitivity] These earplugs are designed for people who are sensitive to sound or have problems with weather-related pressure differences. Conventional sponge filters are completely soundproof, so you can't hear the sounds you need, and it can be difficult to adjust the air pressure, which can be uncomfortable. These earplugs use a newly developed spatial resonator to make them filterless. They block out only the sounds you don't like, and let the sounds and air you need pass through, making them very comfortable. ✅ [For those who are easily affected by the weather] Unlike sponge filter earplugs that completely block out air, these earplugs are designed to allow air to flow by easily adjusting the external and internal pressure. You can also release the internal pressure while wearing them by operating the switch, making it easier to create your preferred environment. ✅ [Comfortable to use] Because these earplugs do not completely block the air, they do not block the inner canal and allow the necessary air to enter, making them very open and less claustrophobic. Even if you don't like the claustrophobic or stuffy feeling of previous earplugs, they are worth using. ✅ [For those who are worried about whether the size of their ears will fit] The size and depth of the ear canals of Japanese people vary widely. We want as many people as possible to be satisfied, so we have prepared a total of 6 types of ear tips to fit as many people as possible. ✅ [Unconditional returns for reasons such as the product not meeting your expectations] If the product you receive does not have the desired effect, is different from what you expected, or is otherwise different from what you expected, we will accept returns unconditionally within 30 days of purchase. In addition, all product returns are handled by Japanese staff, so you can purchase with confidence. ✅ [If you have any questions, we will provide you with consultation support] If you have any questions about how to operate the product, how to install or select accessories, etc., please contact us. We will reply to you via chat or email 24 hours a day. (Access from the included manual) This is a hearing protection product for people with hyperacusis or who are easily affected by weather. It is not suitable for sleeping as it does not completely block out noise, but it can be used by people with hyperacusis as it reduces noise and only lets through comfortable sounds. It provides a comfortable environment inside the ears as it allows sounds necessary for daily life, conversations, and air to pass through.
