✅ [Trademark registration: No ⚠︎The soundproofing effect has been evaluated by many individual and corporate buyers, and some corporations have purchased dozens of units in bulk. It is particularly effective for preventing microphone echo during online meetings, business negotiations, and phone calls. Depending on the purpose of use, the soundproofing effect may not be achieved. This is not a product that completely eliminates sound, but rather a soundproofing product that absorbs some of the sound that reaches you directly and softens the sound, so please consider the purpose and environment of use before making your decision. We have received feedback that the size was larger than expected. Please consider the space you will be using before purchasing.
