Query: Sound not as good as Samsung Level U

I was hoping the Samsung Level U Pro would be a step up from my Level Us that are falling apart. The reviews about to flexible silicon section coming part for the hard plastic is true. It happenes quickly. However, the Level U has far better sound and voice quality than the Level U Pro. I was disappointed with the Pro version and sent it back.
