Very poor quality voice recording

Disappointed for sure. Got it home, figured out how it works and installed the software on my PC in a jiffy, so they get points for ease of use in general. However, the recording quality in XHQ & HQ was maddening. Why even sell a product with such terrible output? Maybe I was so disappointed because my MP3 player, which has a simple recording function in it, did an outstanding job, but lacks the functions needed I'm used to in a recorder. The bottom line is I'm returning it to Best Buy for the Sony P520 model (I believe). If that doesn't meet my demands for voice quality, then I'll try a plug in microphone. Interestingly enough though, my wife's voice sounder much better than mine, but still it didn't sound that much like her.
