I'm so fond of this case, particularly having small children and being a bit clumsy myself. In the 14 months I've had my iPhone, it still looks like new, thanks to my case (and I recently purchased a new one, since my little one decided she'd use the old one for teething, and it is not quite teeth-proof). I've had no issues with sound quality or touch screen difficulty.
One note - I previously had the option of registering for the Total Water Protection Program. Now, apparently, you can only get this coverage by purchasing through a Verizon store. What a disappointment - I ordered this case online via this site, but I would have gone to a local store if I'd known this had changed. Still, it's one of the slimmest, most trustworthy cases I've seen, and I've been through a number of phones and cases over the years. Highly recommended.
