Title: shure with custom earplugs
Review: I tried several other earplugs prior to teh E4c. I have a convertible and a motorcycle and wanted to maintain sound quality even under those circumstances. When even that didn't work all that well I took the plunge and had custom earplugs made by an audiologist. I am not an audiophile but the difference is amazing. Sound isolation is so extreme that I do not use them in the city to avoid becoming road kill.Now that I've tried it I can never go back!
