Soften high notes effectively
More comfortable in my ears than the Etymotic standard size (though I think that is a personal fit issue); slip in easily when moistened.  I thought the case was a frill when I bought them, but it really helps keep them together and clean.  I slip them in and out often during my instrument practice and am much more inclined to stick with the high note practice with this degree of decibel reduction.  Little is lost in sound quality--I tested that by listening to the radio.
