Two piece magnetic ring size choice:

Two piece magnetic ring outer diameter difference of greater vertical height, and its greater resistance, magnetic ring bore must bear the cable to avoid magnetic leakage.

Detachable filter magnetic ring can be used to place all kinds of wire such as: power cable, speaker cable, AV cable, data lines, the electromagnetic field around it improves electromagnetic to avoid outside interference.

Wire harness winding 2 times better. USB data cable on the AV cable video cable audio cable, improving signal quality, radiation shielding. especially in the mouse, the keyboard closer to the computer at one end, effective suppression of electromagnetic radiation.
