I made my own, i got some 2 mm rubber foam and some felt. Used a circle cutter to get nice circles, glued the felt to the foam rubber, used double sided scotch tape to tape the pads to the set, boom, instant silencer, all for about $5 in materials (the circle cutter cost more, but if you have one, or you can use a compass and scissors. Luckily, my ma had one). i had just a slight ammount of sensitivity loss, but not enough that cant be made up for by striking a bit harder. Now that I am used to it, i have no problems at all.
