I have a set from the place that Wingboy suggested and they worked really well. But as we get older the shape of our ear canals change apparently, and in my case has made them EXTREMELY uncomfortable.
I found these at GP Bikes and they are excellent. I wore them faithfully on my recently completed trip around NFLD and home and found them comfortable, even on long days up to 7 hrs.
I used them with my pactalk helmet set so I could listen to entertainment.
