according to what I can find out, a roll of ERS cloth sandwiched between mu-metal...
whatever they are... the work pretty well for me... they seem to remove a layer of smearing and blurring, although the heavier guages of Z-sleeve will add a measure of warmth... this was a perfect tweak for my digital amp... made it significantly less "white" in the sense of high frequency white noise causing the harmonics to grey out. This white-grey tonal problem is common with digital designs... you won't appreciate it until you get rid of it, then WOW... a much better amp right under your nose... the reason for this ? I'd suspect that any conductor is acting like a *hall of mirrors* for the radio frequency region, as well as hyper-audio, even if you can't hear it directly, you sure enough will hear modulation products, like if a digital amp is using a 250 KHz carrier, and you send a 10 Khz wave of energy into it, you will have some 250 Khz pinging back and forth creating nodes, so if one 250 KHz signal meets another one 5 degrees out-of-phase you'd have a 12.5 KHz product, and if this meets a 10 KHz overtone, you'll get some 2.5 (scritchy midrange bark) and some 22.5, right up there in the delicate partials... the idea behind the Z-Sleeve, IMO, is to absorb these reflective "hot spots" without changing the fundamental behavior of the cable too much.... Z-Sleeve have worked well for me in the AC application especially, they take off a coating of grime....
