I was prepared for these to not work at all. I have very small ears. I was surprised when these worked for me. Normal earplugs hurt my ears and never stay in. From the start the packagaing is impressive. They come in a magnetic closure box, that holds the 2 sets of EarPlugs and the carrying case. The carrying case is waterproof and small and clips onto my backpack or keyring. The thing I'm most excited about is the difference these make in practice. They cut down on the overall volume around me, but allow me to hear myself so blending and musicality.
