This pop filter is very functional. It has a long neck to get around almost any mic+shock mount. The neck is okay at not sagging, but you do have to play with the positions to get it where it will stay. This removes all the pops from all the "T"s, "P"s, and "B"s. No reduction of the high end. I did some recordings with and without, and couldn't tell any loss from the high-end frequencies.
