Great protection without compromising quality
Wore these to a concert and they worked great. Turned out I really didn't need them (it wasn't as loud as a typical rock concert), but they were comfortable and dulled the loudness (like bass and screaming fans) while still maintaining a good overall tone, and vocals were still clear. The only complaint was that they can be a bit tough to grasp, both when putting them in and removing them (especially if you put them in too far) - hence the star reduction. Otherwise great.
