Solid earplugs have the most noise reduction. Filtered earplugs or “musician’s plugs” have an opening containing a filter that allows better speech/music reception but still reduce damaging high ambient noise. They are the best choice for those that need to hear surrounding sounds for safety reasons, feel solid plugs give too much noise isolation,or want to keep music levels down but preserve the sound quality. “Stuffy” feeling is reduced compared to solid or foam earplugs. No sense of feeling “cut off.”
