David Taquet 4 It comes with two sets of plugs, the purple one being harder, the blue one is a soft silicone. I tried both, and the purple ones are more effective of you can stand how hard they feel in your ears, or least in mine. The blue set on the other hand, is soft and light enough to wear at night. I live in a very quiet town where a bunch of losers on their modified bikes and sport cars just love to race around, revving their engines as they to forget how lonely and pathetic their lives is by making everyone else miserable until late at night. Well, thanks to these earplugs, I can sleep much better.
