I feel the Fuze Custom Earphones Stephen wrote about will work for me. Just used them on a 6-day ride, had 'em in on average 16 hours a day and I'm very happy with them. They plug right into the audio jack of my 20S, they stay in place, and to me, they block out the road noise like the NRR 32 foam ear plugs did. Tried them as a solution for the ear pain caused by foam ear plugs.
Over the past 5 years/200,000 miles I've used NRR 32 foam ear plugs with a modular helmet and they worked very well keeping things quiet and like others mentioned, cranked the 20S up and could carry on clear rider to rider and phone conversations. However, with the foam ear plugs, experienced same drawback as others, the ear canal hurt, really hurt, and by day four, would consider riding without earplugs all together because my ear canals hurt so bad... but knew that was a dumb thing to do because of the road noise so just put up with the pain. That constant pressure against the ear canal to seal-out noise caused the pain.
The speakers sound great, I now have a wide range of volume control and no more painful ear canals.
BigLew: Tried the ear plugs you mentioned, and they do work very well. I just thought I'd try something that didn't constantly press against the inside of my ear canals.
Thanks everyone for your posts...
