High-density foam acoustic absorption panel, ideal for acoustic treatment. A filter to be placed behind the microphone to prevent reflected sound from the wall from entering the microphone. Sound-absorbing material is provided on the speaker's side to stop the sound, minimizing the impact on the microphone. - Reflection Filter - ¥4,280 - Brand: Frgyee - Specifications: Tri-fold - Size: Width 28cm, Height 19cm - Microphone Stand Extension Tube - ¥432 - Microphone Boom Arm - ¥750 Thank you for viewing. While the reflection reduction effect was sufficient, it didn't quite fit my environment in terms of size, so I'm selling it. I'm including stand extension attachments as peripheral equipment, so please use them as needed. I have hardly used this after opening it, but there may be individual differences in the product, so please check the photos before purchasing. Please note that the shipping label will be affixed directly to the product's outer box.
