Great for musicians
I play guitar in a funk/blues/jazz band, and practices can get quite loud. To protect my hearing, I bought several brands of earplugs including Hearos, Etymotic, and NoNoise (music version). With standard foam earplugs, the high frequencies are disproportionately attenuated such that all you hear is the low (bass) frequencies. As a musician, this is a nightmare--all you can hear are the bass notes and the drummer's kick drum. Of the three brands I've tried, NoNoise does the best job maintaining the high frequencies while reducing the overall volume of the music. There is a tiny bit of roll-off at the highest frequencies, but I was able to play a live show while wearing them. With the other brands (Hearos and Etymotic), the reduction of high frequencies was too great to make them useful on stage. The NoNoise earplugs are the priciest of the bunch, but they are worth the extra cost.
