Re: back pressure - that's what I was most interested in, and I was sad to see it not addressed. I got a silent brass mute for my horn (trombone) a couple of years ago, but found that playing with the mute in (like any other practice mute that I have used) felt extremely different than playing without; especially in lower registers. Even the older version was magical - making me silent but still able to hear myself, but the cost is long term usability.
