Snap on ferrite-core. These ferrite cores have an inner diameter of 5mm. They are designed to remove potential interference and electrical noise from USB cables. They also look pretty cool, wink wink.

These will also fit on paracord mouse cables, but the fit is not perfect, as the paracord sleeving only has an outer diameter of 4mm. They will mostly stay in place, but will move slightly if you attempt to move them manually.
