I have rather petite ears and have a difficult time finding earplugs that fit. The only ones that have worked for me, other than silicone ones - which can block out too much sound for me to converse with people, are some I found on Amazon, called "Vibes High Fidelity Concert Earplugs". They come with three different sizes that are interchangeable and have been working very well for taking the "edge" off of sounds.
