【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

A small type is now available in the long standard earplugs "Classic". The material is PVC foam. NRR=29dB By using finer-grained materials and slightly lowering the volume, we have achieved a more comfortable fit and high sound insulation performance (29dB). Cylindrical earplugs provide a certain level of sound insulation performance without having to be inserted deep into the ear, making them ideal for use by unspecified people.
