Neumann WS2 black

The foam on the bottom is thin, so you need to be careful when putting it on, otherwise you might tear it. The top part is thick, like a double layer. It's round in shape, not exactly the same as the microphone's shape, but this provides flexibility for alignment.

As for its effect on sound, I find that it makes the high frequencies (treble) significantly deeper/muffled. Because of this, I only use it during video conferences; for my regular recordings, I continue to use a pop filter.
