I'm definitely going to be looking for these. For most of my riding around town on errands, I don't wear the Sensaphonics and it would be still nice to know if someone calls me. When I got the 30K Sena, I put the speakers in the one of my helmets for these occasions and these ear plugs may be just what I was looking for to make that work for me.Well, that's exactly what I am saying...using the "baffle" style plugs protects your hearing and allows music to be heard, at least in my case, and that is what you are seeking, right? The foam plugs did not allow it. The noise reduction with the baffle style is still in the mid 20s vs 32/33 for the foam plugs--and that's the highest extant afaik.
For me it was worth the $10 chance I took on them, ymmv, but for me it was all the difference. (Again, credit to JetSpeed for the suggestion)
