Anything with high magnetic permeability will interact with the audio-band magnetic fields. Unless the cable is perfectly coaxial, there will be some audio-band magnetic field outside the cable, where the ferrite device can interact with it. It remains to be demonstrated that the ferrite material is perfectly linear in the audio band before we should believe the assertion that it cannot affect the audio signal.
