Some additional information on the E-A-R HiFi plugs - they are $12 a pair, and have a NRR of 12db, which is sufficient for almost all music applications. For hearing health, you are trying to avoid exceeding an 8-hour time-weighted-average of 85db, as well as avoiding any periods of exposure to 115db continuous, or any peaks at or above 140db (like shotgun blasts) even momentarily. This page has more information, and also some good hearing conservation links at the bottom.
