honestly, I'm not exactly sure what it does in physics terms, they say that their technology is distinct from impedence shifting RF blockers... the construction appears to be a coiled laminate of ERS cloth and a non-magnetic metal. It seems to have some properties in common with Kimber's Palladian AC with the large metal standing wave absorber. They do market AC cords with their Z-Sleeve although they are silent about in wall use. My TV test rig is a fairly absurd aparratus that I find as useful as listening only, when a D.U.T. has a perceptible impact on both the sound and the picture this gives me a more rounded idea of how effective a new thing is destined to be in the audio test system at my office or the groove bomb listening station chez moi. My feeling at this point is that the Z-Sleeve is doing something unlike a ferrite. I do have plenty of "good" ferrite laying about, especially the MIT ferrite terminated power cords. MIT placed a ferrite at either end so any RF would ping pong back and forth until it was finally dissipated as heat. They sound OK in a pinch but not particularly engaging. The Z-stuff seems noticably better at de-whitening and keeping the microdynamic juice flowing. Possibly they found a way to gently drain the RF out without the hard reflections.
