I don't think it's fair to put high quality sound as a requirement for a webcam. A webcam sitting 2-3 feet from you is not going to sound good, especially not with a dinky microphone that has to fit in a device that's 3 inches wide. Even $2,000 cameras have poor sound quality and pretty much everyone who does semi-serious recording (Youtube, etc.) will use an external microphone. Honestly, the classic Logitech c920 is pretty good and it's $60-90 depending on current demand. You can record at 1080p at 30 fps and as long as you have a decent light source ($20 worth of LED lights) the picture quality is quite good.
