Who's using what? likes and dislikes? I'm looking for discreet ear pro that is effective and esy to keep with my kit. The two I've seen being marketed are the OTTE and the Peltor. I remember guys running the Silynx, but haven't heard much about them in awhile. Currently, I have a couple pairs of Comtacs, and a Swatcom.
