Abstract: The present invention incorporates multi-layered insulation that has at least one magnetized layer. The magnetized layer acts to insulate electronic devices, for example highly sensitive audio equipment, from electromagnetic interference and thus, increase the performance of such devices. In this manner, the output from electronic devices, particularly audio equipment, is improved and has less distortion and interference of the original source. A variety of products can be made from the described insulation walls in order to protect electronic device of varying shapes and sizes, as well as allow users of the present invention to choose the direction and orientation of such insulation.
