Yes, some of those tips are specifically for use with in-ear monitors as used by musicians and audiophiles, while others were designed for in-ear ear pro and derived from standard foamies.

Like themonk, I've had the best results from the Comply Professional tips: https://www.complyfoam.com/products/...43214807269563 or https://www.complyfoam.com/products/...41454140489915, the only difference between the two lines is that the latter comes with more tips per package and can be bought in bulk. I use them on both my Ops Core NFMI plugs and on my daily headphones (Shure SE215 at work and SE535 at home/for travel). The Ops Core plugs have an NRR of 30 when used with these tips (which come from the factory with the Comply Professional tips).
