Ear Plugs

I wear the disposable ear plugs now but they give me a headache or earache I suppose. I switched to a brand new pair because the others were getting hard. I thought maybe that was the problem. But the new ones, which are nice and soft, still hurt my ear. Mainly just my left ear. I guess I should look into a different kind. It is difficult to know how they'll fit or work since it usually isn't until the end of my ride that they start to bother me. Hmmm. Some thing to think about and research I suppose.
