I stole this idea from a Youtube channel called Sounds Like a Drum. They used gaff tape to hold a cymbal felt in place on the head. This is ideal because the felt bounces to let the full tone though then suppresses the unpleasant overtones, but not to the point that chokes the snare. It’ very natural sounding.
Below is my creation that tethers a cymbal felt off a rim mount. It’s even adjustable in relation to the edge of the snare.
This is the best dampener that I have ever used. And I have used a lot.
