Excerpt: Do not hesitate to buy these! I use them nearly every weekend for vocals only in small bar band... not only do they provide an amazingly clear and tight vocal sound, but they also put out great low end for music in between sets! It's really surprising! My wife also uses this as her keyboard monitor. She's never been able to hear herself better. They have never left the house without cases... as with any plastic speaker, I'd imagine that they'd scratch.
