I'm in drumline, and things can get pretty loud. Foam earplugs are okay, but they block out a lot of the sound, and can only be used once or twice. These earplugs, however, let you hear just about everything; wether it's a snare shot, a FFFF cymbal roll, or even the sound of your fingers rubbing together, you get quality sound that makes you forget you have them in. The only contrast is that they only have a small piece of plastic so that you can pull them out. If the earplugs aren't attached to the additional wire, they can be very difficult and concerning to pull out.
