I've used a couple of other brands of *high fidelity* earplugs, and they don't compare to Eargasm. First, the fit is key, and not just whether the foam or silicone blocks out sound (kind of a function of width) -- it's important that the length of the earplug is right for your ear canal. This places the sound output at the right place within your ear so that sound quality is best. Second, I love the durability and comfort of the silicone plugs. I can wear these for hours and not get the irritation that I feel with the foam plugs. After several uses, I bought a pair for each member of my family. It's a great investment. Worth every penny.
