I use custom ear molds when on a long distance motorcycle rides. They do provide great isolation and are comfortable for long periods. I've been using the same set for 7 years with no issues. In addition to audiologists, vendors are usually at major motorcycle shows and sometimes at m'cycle shop (espec BMW) open houses.
I still use the Yam headset with my new KX3 as I don't have a boom mic. The Yam works well for long periods too.
