I'll corroborate. I'm a musician, and I can play music wearing Ety-Plugs! (I used to buy the ER-20 "baby blues" but the same object is now called "Ety-Plug.") They are far from perfect, but for the money, they're pretty darn good. (Freq response is not flat. However, it's way flatter than the foam plugs.)
