Query: These harmonicas sound dull

The price and case is nice, but the plastic casing of each harp leaves them dull sounding compared to my other harmonicas. I thought I'd round out my set with all the other keys, but these harps sound like they are playing underwater with no vibrancy. I guess you get what you pay for. Might be okay for a kids starter set, but if you are serious about playing harmonica, look for better quality than this.
