I have been using Etymotic ear plugs for many years and they work well. Regardless of which brand you use it is important to protect your ears at the high levels that occur in some live music venues.

Several years back Roger Waters was in DC and did a presentation of The Wall. The sound system was actually one of the few that was quite good. However, the volume would have been too much without the ear plugs. It was a great performance both sound wise and visually with the large balloons in the shapes of the images on the album floating around the stage.

I have been using Earasers for many years. They work great and keep things fairly safe at rock concerts.
