The result is amazing! It’s funny you mentioned Velcro in your previous post, yeah I was shopping for that just now, I’ll use that and a harness of some kind. Could you hear well in there? A long time ago I bought a small amplifier that goes in the ear (well where else) to compensate for the cowl.
Hats off to you for consider visiting the children’s hospital, I don’t even think I could handle it, and I do work in a hospital but for adults.
