【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. [Sound absorption effect improved by approximately 2.5 times] The sound absorption effect of sound absorption material is determined by the density of the board material. The higher the density, the better the sound absorption and soundproofing effects. By increasing the density of the board material to approximately 200 kg/m³, we have achieved a sound absorption effect approximately 2.5 times that of other companies' products. You can enjoy high quality and clear audio. [Carefully selected materials] YOPIN sound absorbing board is made of environmentally friendly, flame-retardant, high-quality polyester fiber, and is not only odorless and has excellent sound-absorbing effects, but also can be used as a heat-insulating material. Improves the efficiency of air conditioners and realizes energy saving effects. It is delivered uncompressed, so it can be used immediately. [Wide range of applications] The sound absorption panel comes with insect pins for installation, and can be easily installed on walls, doors, and ceilings. Since it is an insect pin, it can be removed without damaging walls etc. It is widely used in bedrooms, piano practice rooms, recording rooms, offices, conference rooms, etc. [Advice] To obtain the ideal sound absorption effect, we recommend that the sound absorption sheet covers at least 70% of the walls in the room. In addition, if you are seeking better sound absorption effects, we recommend using it in conjunction with YOPIN soundproofing material. [About quality assurance] We have carefully selected from a wide variety of sound absorbing materials and strived to provide the most effective ones. You can buy with confidence.
